Abstract: There is provided a shoe capable of suppressing deformation of a member on which the shoe slides. The shoe includes: a first sliding surface which slides on a concave surface of a piston (first movable member); and a second sliding surface which bulges toward a side opposite to the first sliding surface and slides on a flat surface of a swash plate (second movable member). The second sliding surface includes: a curved outer peripheral portion which is provided along an outer periphery of the second sliding surface; and a central portion which is provided at a center of the second sliding surface so as to be continuous with the curved outer peripheral portion and has a radius of curvature greater than a radius of curvature of the curved outer peripheral portion.

Abstract: A swash plate has a base material having an annular shape including a surface facing a mating member, a plurality of grooves extending in a direction intersecting with a sliding direction of the mating member on the entire circumference of the annular shape on the surface, and a resin coating layer formed on the surface and forming a sliding surface with the mating member.

Abstract: There is provided a shoe capable of suppressing deformation of a member on which the shoe slides. The shoe includes: a first sliding surface 210 which slides on a concave surface of a piston (first movable member); and a second sliding surface 220 which bulges toward a side opposite to the first sliding surface 210 and slides on a flat surface of a swash plate (second movable member). The second sliding surface 220 includes: a curved outer peripheral portion 221 which is provided along an outer periphery of the second sliding surface 220; and a central portion 222 which is provided at a center of the second sliding surface 220 so as to be continuous with the curved outer peripheral portion 221 and has a radius of curvature greater than a radius of curvature of the curved outer peripheral portion 221.
