PROBLEM TO BE SOLVED: To prevent an increase in equipment cost by dispensing with a plurality of actuators for moving a plurality of delivering jigs. SOLUTION: A delivering jig 9 moves in a delivering direction when a pusher 39 abuts connection flange 29 by making a delivering cylinder 33 the backward movement limit. By the movement of the delivering jig 9, a piston ring 1 is retained by a holding shaft 5 of a ring magazine 3, wherein its bottom end is pushed to a supply shaft 7 to move so as to fall onto radially movable claws 17. A plurality of the ring magazines 3 are arranged in a row in the direction orthogonal to the sheet in the Figure 1, and respectively accommodate different piston rings. While the claws 17 can be transferred in the direction of the plurality of the ring magazines 3 arranged in a row 3, the delivering cylinder 33 integrally moves in the same direction as the claws 17, whereby the delivering jigs 9 provided corresponding to the respective ring magazines 3 are activated in the delivering direction.
