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.
