(57) A variable displacement compressor 10 includes return springs 9 and 19 that press a swash plate 11 in the axial direction of a drive shaft 8. One end of the return spring 19 is fastened to the swash plate 11, and the other end is fastened to a ring-like (toric) receiving plate 19a through which the drive shaft 8 is inserted. When the swash plate 11 rotates, the return spring 19 and the receiving plate 19a rotate in synchronism with the swash plate 11, and the receiving plate 19a slides in contact with a contact portion la of the cylinder block 1.
