Abstract:
A gap between a vane tip and a cylinder inner circumferential surface is denoted by δ. If rv is set as in an Expression (1), a first vane rotates with the vane tip thereof being out of contact with the cylinder inner circumferential surface. In the vane compressor, wear at the tip of a vane is suppressed, loss due to sliding on bearings is reduced by supporting a rotating shaft portion with a small diameter, and accuracy in an outside diameter and center of rotation of a rotor portion is increased.
