Claims

[Claims for Utility Model Registration] 1. Intervening between relatively moving members, such as the gap between the inner wall surface of the front housing and the vertical surface of the wedge-shaped rotor, or the gap between the inclined surface of the wedge-shaped rotor and the back surface of the planet plate. In a thrust bearing in which two thin annular thrust races are arranged on both front and rear sides of the needle of the thrust needle bearing, there is a thrust race opposite to the needle transfer surface at an appropriate position between the inner and outer peripheral edges of the thrust race. A locking protrusion for preventing rotation is provided that protrudes to the side, and the inner circumferential surface of the front housing, the vertical surface of the wedge-shaped rotor,
A thrust race detent structure in a thrust bearing for an oscillating compressor, wherein a locking recess for engaging the locking convex portion is formed on a race receiving surface such as an inclined surface or a back surface of a plannet plate. 2. The locking convex portion is a locking piece formed by cutting and raising a part of the thrust race so as to be substantially perpendicular to the race;
Alternatively, the thrust race detent structure in a thrust bearing of an oscillating compressor according to claim 1, which is a drawing-formed locking tube portion.
