PROBLEM TO BE SOLVED: To solve problem of a conventional compressor with two coil springs arranged in parallel, which increases man-hours for machining components, and cause failure of easily falling off from a cylinder during assembling and not being assembled. SOLUTION: This rotary compressor is so constituted that a vane presser spring is composed of two components, an outer spring and an inner spring, and the large-diameter part outside diameter of the inner spring is screwed in and integrated with the large-diameter part inside diameter of the outer spring. This constitution can reduce the manhour for machining the components because necessitating only one spring hole for the cylinder and one spring bearing part of the vane and prevent failure caused by falling-off of one of the springs during assembling and not being assembled.
