PROBLEM TO BE SOLVED: To reduce an oil rise quantity by excellently separating oil contained in compressed refrigerant gas, by oppositely arranging at least a single colliding plate to an inner wall peripheral directional outlet part of a sealed vessel, and arranging a stream lining plate for checking a flow of refrigerant gas to an electric motor upper chamber in an upper end part of the colliding plate. SOLUTION: A gas guiding passage frame 14 is provided with a sealed vessel inner wall peripheral directional outlet part 14a opening in the inner wall peripheral direction of a sealed vessel 1 in a position lower than a coil end upper end surface and a second passage directional outlet part 14b opening in the direction of a stator side surface second passage. At least a single colliding plate 14c is oppositely arranged to a sealed vessel inner wall peripheral directional outlet part 14a. A stream lining plate 14d is arranged in an upper end part of the colliding plate 14c. Refrigerant gas flowing out of the sealed vessel inner wall peripheral directional outlet part 14a directly collides with the colliding plate 14c to separate oil containined in the refrigerant gas. A more remarkable oil rise preventive effect can be obtained without scattering the oil separated by the colliding plate 14c in the direction of a compressor part.
