Abstract
A compressor includes a compression mechanism having a ring-shaped first cylinder, a first piston eccentrically rotatable in an interior of the first cylinder, a first cylinder head member disposed adjacent to one axial end of the first cylinder, a second cylinder head member disposed adjacent to an other axial end of the first cylinder, and a fastening bolt. The fastening bolt fastens the first cylinder head member, the first cylinder, and the second cylinder head member together. An end face of the first cylinder head member contacts the first cylinder, and the end face is provided with a protecting groove. The protecting groove is formed closer to a center of the first cylinder than the fastening bolt, and has a groove width smaller than a groove depth of the protecting groove.
