Claims

[Scope of utility model registration request]

The whole has a disk shape and has a through hole in the center, and a guide contact surface that is formed at the inner edge of the through hole and comes into contact with the retainer guide, and a guide contact surface that is located at the same radius outside of the guide contact surface. In a shoe retainer for a swash plate type pump or motor, which has a plurality of shoe insertion holes drilled at intervals in the circumferential direction, the shoe contact surface on the swash plate side that comes into contact with the shoe has a plurality of shoe insertion holes formed at intervals in the circumferential direction. The through hole is provided at a position outward from a concentric circle that divides the through hole into approximately two halves, and the distance from the inside of the shoe contact surface to the guide contact surface forming portion is further than the shoe contact surface. 1. A swash retainer for a swash plate type pump or motor, characterized in that the swash plate is bent away from the swash plate to form a spring acting part.
