    摘要： A compression mechanism that can suppress generation of galling and seizure is provided. The compression mechanism includes a bush 60 including a first sliding surface 61 sliding with an inner surface 45a of a bush hole 45 and a second sliding surface 63 sliding with a side surface 52a of a blade of a piston, and includes at least one of a first bulge 62 formed on one of the first sliding surface 61 and the inner surface 45a such that a gap X between the first sliding surface 61 and the inner surface 45a gradually decreases toward a direction in which lubricant Y is drawn between the first sliding surface 61 and the inner surface 45a along with rocking of the bush 60, and a second bulge 64 formed on the second sliding surface 63 such that the gap X between the second sliding surface 63 and the side surface 52a gradually decreases toward a direction in which the lubricant Y is drawn between the second sliding surface 63 and the side surface 52a along with forward and backward movement of the blade.

    摘要： 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.
