Abstract
The compressor having pistons and a swash plate, the pistons including head portions reciprocatingly inserted in the cylinder bores and neck portions connected to the head portions. A piston rotation restricting structure includes a first rotation restricting member formed with the neck portion of each piston, and a second rotation restricting member provided in the housing. An inclined guide surface is formed in one end surface of the first rotation restricting member and inclined toward the outer peripheral surface for guiding lubricant from the crank chamber into a gap between the first and second rotation restricting members. The inclined guide surface is formed by a single flat surface or two flat surfaces, or in a recessed shape.
