Abstract
In a swash-plate compressor having a shoe slidably coupling a coupling portion of a piston to a swash plate, the coupling portion has a spherical contact surface and the shoe has a spherical surface slidable along the contact surface. At least one of the contact surface and the spherical surface has an oxide film retaining a number of self-lubricating particles. The swash plate is attached to a drive shaft which is rotatable. The piston performs reciprocal movement by the rotation of the swash plate.
