PROBLEM TO BE SOLVED: To provide a highly reliable compressor which achieves long service life by preventing slide wear between a vane and a rotary shaft so that one side surface of the vane does not slide in a state of direct abutment onto the outer peripheral surface of the rotary shaft. SOLUTION: A compressor C is equipped with a compressing element 3 composed of a cylinder 8 which forms a compressing space 21 thereinside, a drive element 2, a rotary shaft 5, a suction and discharge ports, a compressing member 9 which includes a thick part 31 and a thin part 32 continued with one surface thereof inclined and which is disposed in the cylinder 8 to be rotated so as to compress the fluid sucked through the suction port and to discharge the fluid through the discharge port, and a vane disposed between the suction port and discharge port and abutted to one surface 33 of the compressing member 9 so as to partition the compressing space 21 in the cylinder 8 into a low pressure chamber LR and a high pressure chamber HR. A roller ring 40 is inserted and arranged in the outer periphery of the rotation shaft 5 corresponding to the vane so as to abut one side surface of the vane onto the outer periphery of the roller ring 40.
