Abstract
A rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (72), a vane (33), a suction port (20), a discharge port (41), and a partition member (64). The partition member (64) is attached to the lower bearing member (72) so as to form a space enclosed by the partition member (64) and the lower bearing member (72) at a position adjacent to the lower bearing member (72). A portion of an oil stored in the oil reservoir (22) flows into the enclosed space, and thereby an oil retaining portion (53) is formed. The oil retaining portion (53) is located on the same side as the suction port (20) with respect to a reference plane (H1).
