A compressor may include a cylinder block having a plurality of cylinder bores formed therethrough, a drive shaft rotatably supported by the cylinder block, and a swash plate rotatably mounted on said drive shaft. The compressor also may include a plurality of pistons, and each of the cylinder bores may have an outer radial edge. Moreover, each of the pistons may include a head portion which is slidably inserted inside one of the cylinder bores, and a skirt portion which extends from an end surface of the head portion, in which the skirt portion includes a pair of shoe receiving portions. Each piston also may include a rotation prevention portion which is formed at the skirt portion and prevents the piston from rotating about its axis. Moreover, a first separation distance between an axis of rotation of the swash plate and an abutment portion of the rotation prevention portion which slidably abuts an interior wall of a compressor housing is less than a second separation distance between the axis of rotation of the swash plate and a portion of the outer radial edge which edge is furthest from the axis of rotation of the swash plate.
