Claims

[Scope of utility model registration request]

A large number of needles held by retainers are provided 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, and/or the gap between the inclined surface of the wedge-shaped rotor and the back surface of the planet plate. In a thrust bearing for a rocking compressor in which a thin plate annular thrust race is interposed on both the front and rear sides of the needle, a relatively moving member such as the inner wall surface of the front housing and/or the back surface of the plannet plate; A retainer receiving ring portion formed in an L-shaped cross section is fitted into the annular fitting step portion formed on the stationary side member at the inner peripheral edge of the thrust race located on the side of the fitting step portion. At the same time, the outer peripheral edge of the thrust race located on the side of the rotating member such as the wedge-shaped rotor is formed into an L-shaped cross section to form a fitting ring portion, and the ring portion is attached to the outer peripheral surface of the rotating member. Thrust race mounting structure in the thrust bearing of a fitted oscillating compressor.
