There is provided a vane compressor in which a vane is stably supported, the wear at the tip of the vane is suppressed, the loss due to sliding on bearings is reduced by supporting a rotating shaft portion with a small diameter, and the accuracy in the outside diameter and the center of rotation of a rotor portion is increased. To allow a bush (8) to stably rotate about a bush center (8a), an end of a vane portion (6a) that is close to an inner circumferential surface center is always positioned on the inner side with respect to the bush center (8a).
