ABSTRACT:
In a swash plate type compressor in which a piston (60) is reciprocated in accordance with a rotary motion of a swash plate and is located within a housing (2) having an inner periphery (2a), the piston is formed with first and second rotation-regulating surfaces (62a, 63a) which face the inner periphery and have centers of curvature at positions different from one another. The first and second rotation-regulating surfaces are angularly offset from one another. It is preferable that the curvature of each of the first and second rotation-regulating surfaces is equal to or smaller than that of the inner periphery of the housing.
