PURPOSE: To provide compact and light body of parts inserting equipment by providing a revolution stopper having a plurality of devices to stop a parts holder and to prevent its revolution, and a device to move the parts holder parallel to a revolving axis.

CONSTITUTION: A rotation position 0° is regulated in such a state that a stopper metal 21 contacts with a stopper screw 28a of an end stopper 26 at anticlockwise rotation. A rotation position 270° is regulated in such a state that the stopper metal 21 contacts with a stopper screw 28b of the end stopper 26 at clockwise rotation. A rotation position 90° is regulated in such a state that air is supplied to a cylinder 35a lowering a stopper pin 32a at clockwise rotation and the stopper metal 21 contacts with the stopper pin 32a. A rotation position 180° is regulated in such a state that air is supplied to a cylinder 35b lowering a stopper pin 32b and the stopper metal 21 contacts with the stopper pin 32b.
