Abstract

To allow a bush to stably rotate about a bush center, an end of a vane portion that is close to an inner circumferential surface center is always positioned on the inner side with respect to the bush center. Thereby, in a vane compressor a vane is stably supported, wear at a tip of the vane is suppressed, loss due to sliding on bearings is reduced by supporting a rotating shaft portion with a small diameter, and accuracy in outside diameter and center of rotation of a rotor portion is increased.
