This invention aims at obtaining an oil feed mechanism-carrying rotary compressor capable of increasing a feed rate of an oil to a sliding portion, improving a lubricating effect and a cooling effect, and discharging abrasion powder and dust from an oil feed system. To achieve this object, the present invention is formed by providing a bottomed cylindrical oil bore (213) in the central portion of a shaft (206), and a spiral oil groove (224) in an outer circumferential surface thereof, allowing communication between one end portion of the oil bore (213) and one end portion of oil groove (224), i.e. between a bottom portion (213') and an end portion (224') via an outlet port (214), and providing a suction passage (221A) for allowing communication between the other end of the oil bore (213) and an oil (2), and a discharge passage (223B) for communication between the other end (224') and the oil (2).
