Patent attributes
A fastening tool includes a tool body, an anvil, a pin-gripping part, a motor, a rotation member, a moving member, a gear part and a receiving member. The rotation member is configured to be rotationally driven around the driving axis. The moving member is coupled to the pin-gripping part and engaged with the rotation member. The moving member is configured to move along a driving axis defining a front-rear direction, in response to rotational driving of the rotation member. The gear part is shaped like a flange projecting radially outward from an outer peripheral surface of the rotation member, and has gear teeth on an outer circumference thereof. The receiving member is disposed rearward of the gear part and configured to receive, via a rear surface of the gear part, a rearward reaction force applied to the rotation member when the pin-gripping part moves frontward.
