| Disclosed is a rotary compressor wherein the ratio of a first bearing gap between the inner circumferential surface (32b) of a roller (32) and the outer circumferential surface (31b) at the eccentric portion (31a) of a crankshaft (31) and the diameter at the eccentric portion (31a) of a crankshaft (31) is set in the range of 11/10000-20/10000, the roller (32) can be pressed lightly against the inner circumferential surface (30a) of a cylinder by the differential pressure between a high pressure portion and a low pressure portion, and since the minimum gap (W) during operation is minimized and the inner circumferential surface (30a) of a cylinder can be touched only with the differential pressure, big sliding loss is not generated. Consequently, high efficiency can be attained by reducing leakage from the minimum gap (W) during operation while controlling degradation in reliability due to abrasion or seizure and, as a result, leakage loss from the minimum gap (W) during operation is reduced thoroughly without degrading reliability, and the efficiency of a compressor is enhanced furthermore without increasing the sliding loss. | ||||||
