A rotary compressor (100) has a sealed container (1), a cylinder (15), a piston (28), a bottom bearing member (72), a vane (33), an intake port (20), a discharge port (41), and a partitioning member (64). The partitioning member (64) is attached to the bottom bearing member (72), thereby forming a space enclosed by the partitioning member (64) and the bottom bearing member (72) at a position adjacent to the bottom bearing member (72). An oil retaining part (53) is formed by a portion of oil that has accumulated in an oil reservoir (22) entering the enclosed space. The oil retaining part (53) is positioned on the same side as the intake port (20), as viewed from a reference plane (H1).
