PROBLEM TO BE SOLVED: To facilitate deburring work, and improve productivity by molding a ring shaped part whose width is widened at both sides of claw parts so as to make to the same surface as an outer peripheral surface of the claw parts protruded from the ring shaped part of an Oldham's coupling for composing a detent mechanism of a scroll compressor. SOLUTION: Claw parts 41, 40 wherein a pair of key grooves arranged on a main bearing member and a turning spiral impeller member are slid and fitted to a pair of key grooves of a turning end plate are formed in an Oldham's coupling 15. In this case, a surface faced to a ring center of each claw 40, 41 is formed on the same surface as an inner circumferential surface 42 of a ring shaped part 34, the claw 41 formed on a lower surface is formed in a width similar to that of the ring shaped part 34, and the claw 40 formed on an upper surface is protruded from the ring shaped part 34 to an outer peripheral side. The width of the ring shaped part 34 is widened at both ends of the claws 40, 41 so as to form both sides of the claw 40 formed on the upper surface similar to a surface 43 protruded in an outer peripheral direction of each claw 40, 41. It is thus possible to facilitate deburring work in the case where the claw part 40 is worked in a fitting size of a key groove.
