The invention provides a sealed motor drive compressor which can prevent the bubble generation in the lubricant near the front end of a crankshaft as much as possible and can stably supply lubricant to the sliding parts such as piston and etc.. A flow block member 30 comprises a fixed part 31 which is fixed at the central position between the center of the bottom surface of the sealed container 1and the outer edge and a block part 32 bended from the fixed part into a right angle. In order to block the lubricant flow generated by the rotation of the crankshaft 6, the overlook longitudinal direction of the block part 32 points the outer edge from the bottom center of the sealed container 1, i.e. orthogonal with the flow direction of the lubricant, and reducing the area of the fixed part 31, at least less than the area of the block part 32 so as to make it easy to fix the fixed part 31 on the bottom surface of the sealed container 1 which is not always a planar.
