A closed compressor is provided with a flexible oil fence, of which a fixed portion as one end is fixed onto an upper surface of a cylinder between a shaft and a cylinder head and a free end as the other end extends toward an upper inner surface of a closed container. According to this configuration, a collision sound can be prevented from being generated even when the oil fence collides with the upper inner surface of the closed container and hot oil can be prevented from flowing along a surface of suction muffler.
