Abstract: A fastening tool includes: a cylindrical rotation guide member extending in one direction and rotatably supported; a holding member having an opening in which a driver bit is detachably inserted, and configured to move in an axis direction along the extension direction of the rotation guide member inside the rotation guide member and to rotate together with the rotation guide member; and a moving member configured to move the holding member in a front and rear direction along the rotation guide member; a rotation member; and a transmission member connected to the moving member and having flexibility to be wound along an outer periphery of the rotation member. The rotation member is rotated by the motor, so that the moving member is moved with the transmission member in one direction in which a screw engaged with the driver bit is pressed against a fastening target.

Abstract: A fastening tool includes: a bit holding portion which detachably holds a driver bit and is configured to rotate in a circumferential direction of the driver bit and move in an axial direction of the driver bit; a first motor configured to rotate the bit holding portion; a second motor configured to move the bit holding portion along the axial direction; and a control unit configured to control a position of the bit holding portion along the axial direction by the number of rotations of the second motor. The control unit is configured to control a moving speed of a screw moved by rotation of the first motor or a rotation speed of the first motor.
