Abstract: PURPOSE:To prevent deterioration of the quality without damaging works by a feeding claw member by removing the feeding claw member from a recessed part of the work by a first cam member when the feeding claw member returns from the finishing position to the starting position, and hooking the feeding claw member to the recessed part of the following work by a second cam member. CONSTITUTION:When a sliding member moves along a guide rail, a feeding base 20 fixed to the sliding member moves to the finishing position, the inclined surface of a second cam member 52 is brought into contact with a bearing member 32, and a feeding claw member 30 is swayed clockwise aroung a fulcrum pin 28. A hooking projection 31 of the feeding claw member 30 is hooked to a recessed part W1 of a work (W), and moves the work (W). When the feeding base 20 moves to the starting position, the inclined surface of a first cam member 53 is brought into contact with a bearing member 33, and the feeding claw part 30 is swayed counterclockwise around the fulcrum pin 28. This arrangement allows the hooking projection 31 of the feeding claw member 30 to be released from the recessed part W1. Thus, the circumferential edge and side edge part of the recessed part W1 are not damaged.
