Claims

[Scope of utility model registration request]

It is slidably inserted into the vane groove of the cylinder from the base side via a spring, and the tip part is in sliding contact with the outer peripheral surface of the rolling piston, and the compression chamber formed by the cylinder and rolling piston is connected to a high pressure chamber and a low pressure chamber. In a rotary compressor equipped with a vane that is partitioned into two parts, a first tapered surface and a second tapered surface that are parallel to each other are provided near the base of the surface of the vane on the high-pressure chamber side and near the tip of the surface of the vane on the low-pressure chamber side. A rotary compressor characterized by having a tapered surface.
