摘要： The purpose of the present invention is to suppress noise caused by contact between a depression and a ring. Provided is an electric compressor comprising: a housing that forms an outer shell; a fixed scroll that is housed in the housing and fixed on the housing side; a turning scroll that meshes with the fixed scroll and turns with respect to the fixed scroll; an autorotation inhibiting mechanism (30) that inhibits autorotation of the turning scroll; and a lubricant supply unit that supplies a lubricant to the autorotation inhibiting mechanism (30). The autorotation inhibiting mechanism (30) has: a ring hole (32) which is formed in the turning scroll; a ring (33) which is disposed in the ring hole (32), and the outer circumferential surface (33b) of which faces the inner circumferential surface 32a of the ring hole (32); and a pin (34) which is provided to the housing and which engages with the inner circumferential surface (33a) of the ring (33). A gap (G) formed between the inner circumferential surface (32a) of the ring hole (32) and the outer circumferential surface (33b) of the ring (33) is 0.1-0.6 mm.
