Abstract
There is provided a driving machine capable of reducing a load applied to a guide member in a direction of a center axis. The driving machine drives a fastener into a workpiece. The driving machine includes a movable piston, a driver blade operating together with the piston and applying driving force to the fastener, a cylinder guiding operation of the piston, a holder provided in a housing and supporting the cylinder, and a vibration damping rubber interposed between the holder and the housing and receiving a load applied to the holder in an operational direction of the piston.
Claims13
A driving machine for driving a fastener into a workpiece, the driving machine comprising:
- a piston;
- a cylinder in which the piston travels in a first direction and a second direction opposite the first direction;
- a compression chamber configured to be filled with a gas for moving the piston in the first direction;
- a damper configured to absorb a kinetic energy of the piston;
- a striker coupled to the piston and configured to apply driving force to the fastener;
- a motor;
- a drive shaft coupled to the motor, the drive shaft extending in a direction crossing a traveling direction of the piston;
- a rotary component coupled to the drive shaft and configured to, when rotated by the motor, move the striker in the second direction;
- and
- first and second bearings disposed to sandwich the rotary component and support the drive shaft.
