Abstract
Disclosed herein is a vane rotary compressor in which a fluid such as a refrigerant is compressed while a volume of a compression chamber is reduced during rotation of a rotor. There is provided a vane rotary compressor capable of preventing a delay of rotation operation of a vane by respectively forming oil films on both sides of a hinge portion of the vane in a rotation direction thereof and smoothly sliding the hinge portion.
