Claim:
1. A compressor comprising: a cylinder including a cylinder chamber with an inner circumferential surface that is a substantially cylindrical surface; a shaft including a main shaft and an eccentric part, which is eccentric relative to the main shaft; a roller part having an inner circumferential surface fitted on an outer circumferential surface of the eccentric part, the outer circumferential surface being a substantially cylindrical surface, and being placed in the cylinder chamber so as to make an orbital motion; a blade part along with the roller part partitioning inside of the cylinder chamber into a low-pressure chamber and a high-pressure chamber; and bearing parts fixed to the cylinder and respectively including cylindrical surfaces supporting the main shaft, a relation (φDs−φDr)/2<ε being satisfied, in which central axes of the cylindrical surfaces of the bearing parts being eccentric relative to a central axis of the inner circumferential surface of the cylinder chamber, and the bearing parts being sliding bearings.
