Title: DRIVER, STRIKE MECHANISM, AND MOVEMENT MECHANISM
Abstract:
Provided is a driver configured so that an increase in the load torque of a motor can be prevented when moving, using the torque of the motor, a strike mechanism against the force of a first movement mechanism. This driver is provided with: a strike mechanism 12 capable of moving in a first direction B1 and a second direction B2 which is opposite the first direction B1; and a first movement mechanism for moving the strike mechanism 12 in the first direction B1 to strike a fastener. The driver has: a motor; a second movement mechanism 45 rotated by the torque of the motor and moving the strike mechanism 12 in the second direction against the force of the first movement mechanism; and a torque suppression mechanism 45A-45H for suppressing an increase in the torque of the motor when moving the strike mechanism 12 in the second direction B2.
