The hinge mechanism is arranged in the compressor between the lug plate (17) and the cam plate (18). The hinge mechanism includes a support (20) formed on the cam plate. A spherical projection (23) extends from the support in a direction rearward with respect to the direction a drive shaft (16) rotates. A roller (22) extends from the support in a direction forward with respect to the direction the drive shaft rotates. A first cam (24) is formed on the lug plate surrounding and guiding the spherical portion. A second cam (25) is formed on the lug plate. The second cam includes a cam surface that contacts and guides the roller.
