The invention provides a vane rotary type fluid device and a compressor capable of reducing the loss due to the sliding of the front end of a vane on the inner circumferential surface of a cylinder and improving the compression or expansion efficiency. A compression element (12) and an electric element (15) served as the driving source of the compression element (12) are arranged inside an enclosed container. The compression element (12) is equipped with a shaft (6), a roller (7), a cylinder (5), two bearings (3, 4), a separation vane (8), a suction inlet (18), an outlet (19) and a position restriction mechanism. The position restriction mechanism limits the position of the front end of the vane (8), so that the front end of the vane is placed along the inner circumferential surface of the cylinder (5). The position restriction mechanism is equipped with an annular groove (17) formed on at least one of the two bearings (3, 4) and on a concentric circle of the inner circumferential surface of the cylinder (5) and a ring (9) combined with the front end of the vane (8) and slidably and freely arranged inside the annular groove (7). |
