Variable capacity compressor

This variable capacity compressor comprises: a housing; a piston; a drive shaft rotatably supported by the housing; a rotor that rotates in unison with the drive shaft; a swash plate that rotates in synchronism with the rotation of the rotor coupled via a coupling means; a conversion mechanism that converts the rotation of the swash plate into a reciprocating motion of the piston; and a pressure control valve that is capable of controlling the internal pressure of a crank chamber. The variable capacity compressor is characterized in that: the coupling means directly or indirectly couples a first arm projecting from the rotor and a second arm projecting from the swash plate; and the drive shaft is eccentrically passed through a through hole that is pierced through the swash plate. With this configuration, it is possible to provide a variable capacity compressor in which the behavior of the swash plate can be stabilized with a simple structure and in which the swash plate can be inclined smoothly.
