Claims

[Scope of utility model registration request]

A concave groove is provided in a bearing that closes the end face of the cylinder.In a compressor where the open side of the concave groove is closed with a cover and used as a cavity, etc., the top surface of the convex part on the bearing side that contacts the cover is all on the same plane. A compressor, wherein the cover and the top surface of the convex portion are brought into direct surface contact without using a sealing member, and the cover is fixed to the cylinder end surface of the bearing by a fixing bolt.
