Claims

[Scope of utility model registration request]

(1) A piston that eccentrically rotates inside the cylinder, a vane that comes into contact with the outer periphery of the piston and slides back and forth in a vane groove provided in the cylinder, and a cylinder chamber that closes both end surfaces of the cylinder. In a rotary compressor comprising a main bearing and an end bearing, the main bearing or the end bearing having a discharge hole, which corresponds to the discharge hole provided in the main bearing or the end bearing in the inner wall of the cylinder. A rotary compressor characterized in that a concave portion is provided across the axial direction of the cylinder at a position where the cylinder has a concave portion.

(2) Utility model registration claim No. (1) characterized in that the recess is separated from the vane groove provided in the cylinder.
The rotary compressor described in Section 1.
