According to the present invention, when the golf putter hits the golf ball, as spin of the golf ball is smoother, directionality of the golf ball is increased. ## Claims ### Claim 1 A golf putter head, comprising: a head body; and a hitting member provided at a front of the head body for hitting a ball, and to be freely slidable up and down within a predetermined range with respect to the head body, wherein the hitting member is shaped into a plate and at least one sliding part sliding with respect to the head body is provided on a side opposite to a golf ball hitting surface of the hitting member. ### Claim 2 (depends on 1) The golf putter head of claim 1, wherein, at the front of the head body, a guide member having a predetermined height is provided on a position corresponding to the at least one sliding part to guide sliding of the at least one sliding part of the hitting member within a predetermined range. ### Claim 3 (depends on 2) The golf putter head of claim 2, wherein at least one ball bearing for smooth sliding is disposed between the guide member and the at least one sliding part. ### Claim 4 (depends on 1) A golf putter comprising: the golf putter head according to claim 1; and a handle connected to the head body of the golf putter head. ### Claim 5 (depends on 4) The golf putter of claim 4, wherein the head body includes a front body and a rear body, and the handle of the golf putter is connected to the rear body. ### Claim 6 A golf putter head, comprising: a head body; and a hitting member provided at front of the head body for hitting a ball, and to be freely slidable up and down within a predetermined range with respect to the head body, wherein the head body includes a front body in which the hitting member is mounted and a rear body provided to slide freely in a back and forth direction with respect to the front body. ### Claim 7 (depends on 6) The golf putter head of claim 6, further comprising: at least one buffer provided between the front body and the rear body. ### Claim 8 (depends on 7) The golf putter head of claim 7, wherein the at least one buffer is one of a sponge, a spring, a cylinder, and a shock absorber. ### Claim 9 (depends on 6) The golf putter head of claim 6, further comprising: a lifting device for actively lifting the hitting member with respect to the head body by transmitting compressive force between the front body and the rear body to the hitting member when a putter hits a golf ball. ### Claim 10 (depends on 6) The golf putter head of claim 6, wherein the rear body includes at least one horizontal rack gear at a front surface thereof, and the front body includes a pinion gear which is rotated on a shaft parallel with a longitudinal direction of the front body by back and forth movement of the horizontal rack gear, and the hitting member is provided with a vertical rack gear at a rear surface thereof which the rack gear moves up and down by rotation of the pinion gear. ### Claim 11 (depends on 10) The golf putter head of claim 10, wherein the pinion gear comprises a first pinion gear and a second pinion gear which have different diameters and are disposed on a rotational shaft, and one of the first and the second pinion gear is connected to the horizontal rack gear, and the other one is connected to the vertical rack gear. ### Claim 12 (depends on 6) The golf putter head of claim 6, further comprising: an extension part included in the hitting member and projecting upwardly above an upper surface of the head body; a first hinge connector provided on an upper end of the extension part; a second hinge connector provided on an upper surface of the rear body; and a rod including a first and a second end which are respectively hinged to the first hinge connector and the second hinge connector. ### Claim 13 (depends on 6) The golf putter head of claim 6, further comprising: a first cylinder horizontally provided at rear of the front body; a second cylinder vertically provided on a upper part of the front body; and a flow path communicating from inside of the first cylinder to inside of the second cylinder, wherein the first cylinder includes a first piston rod extended toward the rear body, the second cylinder includes a second piston rod extended upward, and the hitting member includes a connecting part extended in contact with an upper end of the second piston rod. ### Claim 14 (depends on 13) The golf putter head of claim 13, wherein a diameter of the first cylinder is larger than a diameter of the second cylinder. ### Claim 15 (depends on 13) The golf putter head of claim 13, wherein the first and the second cylinder are a hydraulic cylinder or a pneumatic cylinder. ### Claim 16 (depends on 6) The golf putter head of claim 6, wherein, any one of the front body and the rear body is provided with at least one hole penetrating the body in the back and forth direction, and the other one thereof is provided with a shaft penetrating the at least one hole. ### Claim 17 (depends on 16) The golf putter head of claim 16, wherein any one of the front body and the rear body is provided with a linear bush to smooth linear motion in the back and forth direction of the shaft moving through the at least one hole. ### Claim 18 (depends on 16) The golf putter head of claim 16, wherein the shaft is provided with a shock absorbing member on an outer circumference thereof to relieve shock between the front body and the rear body. ### Claim 19 (depends on 6) A golf putter comprising: the golf putter head according to claim 6; and a handle connected to the head body of the golf putter head.
