Variable displacement compressor

A variable displacement compressor comprising:

• a housing defining a cylinder bore;
• a piston located in the cylinder bore;
• a drive shaft rotatably supported by the housing;
• a rotor mounted on the drive shaft to rotate integrally with the drive shaft;
• a swash plate of an aluminum alloy material, the swash plate being connected to the piston to convert rotation of the drive shaft to reciprocation of the piston, wherein the swash plate is supported on the drive shaft, the swash plate includes a through-hole defined by a wall of the alluminum alloy material that includes an engaging section, the engaging section always engaging the drive shaft during rotation of the swash plate, and the swash plate inclines and slides axially along the drive shaft to vary the piston stroke and change the displacement of the compressor;
• and
• a hinge mechanism located between the rotor and the swash plate for rotating the swash plate integrally with the rotor and for guiding the motion of the swash plate, the hinge mechanism comprising a first hinge part connected to the aluminum alloy material of the swash plate, a second hinge part extending from the rotor, and a pin attached to the first hinge part and having an end extending from the first hinge part to the second hinge part, wherein the first hinge part is made of an iron-based metal material and includes a mounting hole in which the pin is press fitted, and the second hinge part includes a guide hole for receiving the end of the pin to guide movement of the first hinge part relative to the second hinge part.
