The tool driving mechanism is configured to hold a tool and apply a rotation operation and a feeding operation in a tool axis direction to the tool. The driving mechanism fixing instrument has a through hole through which the tool passes. The driving mechanism fixing instrument is configured to be inserted detachably into a guiding through hole in order to fix the tool driving mechanism to a drill jig in which the guiding through hole is formed. ## Claims ### Claim 1 A drill driving apparatus comprising: a tool driving mechanism configured to hold a tool and apply a rotation operation and a feeding operation in a tool axis direction to the tool; and a driving mechanism fixing instrument, having a through hole through which the tool passes, configured to be inserted detachably into a guiding through hole from only a tool side in order to fix the tool driving mechanism to a drill jig in which the guiding through hole is formed, wherein the driving mechanism fixing instrument has a guide that has a smaller outer shape than the guiding through hole in order to be able to be inserted into the guiding through hole, the guide widening in an interior of the guiding through hole in a radial direction of the guiding through hole when the tool driving mechanism is rotated relative to the drill jig in an opposite direction to a rotation direction of the tool, wherein the driving mechanism fixing instrument is configured to sandwich the drill jig by pressing the guide against a chamfer formed in a workpiece side of the guiding through hole, the chamfer being formed to fit with the guide when the outer shape of the guide widens, wherein the driving mechanism fixing instrument is fixed to the drill jig when the tool driving mechanism is rotated relative to the drill jig in the opposite direction to the rotation direction of the tool, and wherein the driving mechanism fixing instrument comprises: a first guide having a surface that contacts the drill jig, wherein the surface moves away from the tool driving mechanism when the tool driving mechanism is rotated relatively in the opposite direction to the rotation direction of the tool; a second guide comprising the guide that widens in an interior of the guiding through hole in a radial direction of the guiding through hole when the tool driving mechanism is rotated relative to the first guide in the opposite direction to the rotation direction of the tool; and a third guide comprising a tapered portion, the tapered portion being fixed to the tool driving mechanism and widens the guide that widens in the radial direction of the guiding through hole when the surface of the first guide that contacts the drill jig moves away from the tool driving mechanism. ### Claim 2 (depends on 1) A drill driving method comprising: utilizing the drill driving apparatus of claim 1; and applying a rotation operation and a feeding operation in a tool axis direction to the tool in a condition where the tool is held by the tool driving mechanism. ### Claim 3 (depends on 2) The drill driving method according to claim 2, wherein the guide that widens in an interior of the guiding through hole in the radial direction also compresses in the interior of the guiding through hole in the radial direction. ### Claim 4 (depends on 1) The drill driving apparatus according to claim 1, wherein the guide that widens in an interior of the guiding through hole in the radial direction is formed to also compress in the interior of the guiding through hole in the radial direction. ### Claim 5 (depends on 4) The drill driving apparatus according to claim 4, wherein the guide that widens and compresses in an interior of the guiding through hole in the radial direction has an axially extending slit. ### Claim 6 (depends on 4) According to claim 4, wherein the guide that widens and compresses in an interior of the guiding through hole in the radial direction has a deformable free end configured for reception within a chamfered recess formed in one of opposing surfaces of the drill jig that is oriented for positioning closest to a workpiece to be worked. ### Claim 7 A drill driving apparatus comprising: a tool driving mechanism configured to hold a tool and apply a rotation operation and a feeding operation in a tool axis direction to the tool; and a driving mechanism fixing instrument having a through hole through which the tool passes, the driving mechanism fixing instrument being configured to be inserted detachably into a guiding through hole in a drill jig in order to fix the tool driving mechanism to the drill jig, wherein the driving mechanism fixing instrument comprises: a first guide having a surface that contacts the drill jig, wherein the surface moves away from the tool driving mechanism when the tool driving mechanism is rotated relatively in an opposite direction to a rotation direction of the tool; a second guide that widens in an interior of the guiding through hole in a radial direction of the guiding through hole when the tool driving mechanism is rotated relative to the first guide in the opposite direction to the rotation direction of the tool; and a third guide that is fixed to the tool driving mechanism and widens the second guide in the radial direction of the guiding through hole when the surface of the first guide that contacts the drill jig moves away from the tool driving mechanism, and wherein the driving mechanism fixing instrument is configured to fix the tool driving mechanism to the drill jig by sandwiching opposing surfaces of the drill jig, between which opposing surfaces the guiding through hole extends. ### Claim 8 (depends on 7) The drill driving apparatus according to claim 7, wherein the first guide is connected to the tool driving mechanism by a groove having a length direction that inclines relative to the tool axis direction and a projection that moves along the groove. ### Claim 9 (depends on 7) The drill driving apparatus according to claim 7, wherein the driving mechanism fixing instrument exerts a force on the drill jig in a normal direction of a tapered portion. ### Claim 10 (depends on 7) The drill driving apparatus according to claim 7, wherein the first guide is provided with at least one of either a whirl-stop pin and an antiskid member for suppressing rotation of the first guide relative to the drill jig. ### Claim 11 A drill driving apparatus comprising: a tool driving mechanism configured to hold a tool and apply a rotation operation and a feeding operation in a tool axis direction to the tool; and a driving mechanism fixing instrument having a through hole through which the tool passes, the driving mechanism fixing instrument being configured to be inserted detachably into a guiding through hole in a drill jig in order to fix the tool driving mechanism to the drill jig, wherein the driving mechanism fixing instrument comprises: a first guide having a surface that contacts the drill jig, wherein the surface moves away from the tool driving mechanism when the tool driving mechanism is rotated relatively in an opposite direction to a rotation direction of the tool; a second guide that widens in an interior of the guiding through hole in a radial direction of the guiding through hole when the tool driving mechanism is rotated relative to the first guide in the opposite direction to the rotation direction of the tool; and a third guide that is fixed to the tool driving mechanism and widens the second guide in the radial direction of the guiding through hole when the surface of the first guide that contacts the drill jig moves away from the tool driving mechanism. ### Claim 12 (depends on 11) The drill driving apparatus according to claim 11, wherein the first guide is connected to the tool driving mechanism by a groove having a length direction that inclines relative to the tool axis direction and a projection that moves along the groove. ### Claim 13 (depends on 11) The drill driving apparatus according to claim 11, wherein the third guide is provided with a tapered portion for widening the second guide, and the driving mechanism fixing instrument exerts a force on the drill jig in a normal direction of the tapered portion. ### Claim 14 (depends on 11) The drill driving apparatus according to claim 11, wherein the first guide is provided with at least one of either a whirl-stop pin and an antiskid member for suppressing rotation of the first guide relative to the drill jig.
