Claims

[Claims for Utility Model Registration] A forward/reverse motor is fixed to a driver stand that moves up and down by the operation of an elevating drive source so as to move together, and the forward/reverse motor is driven via a transmission mechanism having a connecting shaft to the drive shaft of the forward/reverse motor. In an automatic screw tightening machine with a connected driver, a guide stand that rotatably guides the connecting shaft is attached to the driver stand, a motor mounting case with a forward/reverse motor fixed to this guide stand is rotatably placed, and the bolts are attached to the guide stand. At the same time, the reversing lever, which rotates only in the forward rotation direction, is fixed to the connecting shaft via a one-way clutch, while the motor mounting case has a locking part that protrudes onto the path of movement of the reversing lever. A fixed-angle reversing device characterized in that a reversing stopper is fixed and a forward rotation stopper is provided on a guide stand to protrude onto a moving path of a reversing lever.
