The fixed scroll peripheral wall includes a plurality of thick-walled portions spaced from each other in the circumferential direction of the fixed scroll peripheral wall. A groove is formed in at least one of end surfaces of the plurality of thick-walled portions facing the elastic plate, and accommodates elastic deformation of the elastic plate so that a backpressure chamber and an intake passage are in communication with each other when a pressure difference between the backpressure chamber and an intake passage exceeds a predetermined value.
