1. A rotating main shaft that is rotationally driven around a predetermined axis, and a support ear that is provided on one side in the axial direction so as to have a variable inclination angle with respect to the rotating main shaft. A rotor arm having a drive ear that is fixed to the rotation main shaft and that engages with the support ear of the swash plate in the rotational direction, and a swash plate that engages with the peripheral edge of the swash plate. In a swash plate type variable displacement compressor including a piston driven to reciprocate according to rotation, the rotor arm has a support receiving surface that receives the drive ear and restricts the inclination angle, and the drive ear Are arranged in a pair so as to sandwich the support ear, and the drive ear located on the rear side in the rotation direction of the pair of drive ears is located closer to the predetermined axis than the drive ear located on the front side in the rotation direction. Characterized by protruding toward the heart Swash plate type variable capacity compressor.
