Abstract

In the compressor of the present invention, guide surfaces 57a and 57b are formed on a lug plate 51 and guided surfaces 59a and 59b are formed on swash plate arms 5e and 5f. The guide surfaces 57a and 57b and the guided surfaces 59a and 59b are respectively in linear contact with one another at a first abutment position P1 when an inclination angle is maximum and are in linear contact with one another at a second abutment position P2 when the inclination angle is minimum. The guide surfaces 57a and 57b are formed such that portions between the first abutment position P1 and the second abutment position P2 are convex toward the guided surfaces 59a and 59b. In the compressor, a contact angle θ1 at the first abutment position P1 can be made large, and a contact angle θ2 at the second abutment position P2 can be made small.
