Claims

[Scope of utility model registration request]

A rolling piston installed in the cylinder is driven by a crankshaft, and eccentric rotation is performed while the rolling piston is in contact with the inner wall of the cylinder.
2 by bringing the vane into contact with the rolling piston;
In a rotary compressor that sucks and compresses gas while forming two working chambers, an elastic plate-like body is provided between the housing of the rotary compressor and the rolling piston to sandwich the cylinder, respectively; The housing is provided with a pressure guiding hole that communicates between the plate-shaped body and the shell of the rotary compressor, and when high-pressure gas in the shell of the rotary compressor is introduced between the housing and the plate-shaped body, protruding deformation occurs. A vane structure for a rotary compressor, characterized in that the width of the vane in the direction of the two plate-like bodies on the rolling piston side is formed to be slightly smaller in order to prevent contact between the vane and the plate-like body. .
