PROBLEM TO BE SOLVED: To provide a compressor high in reliability to reduce a pushing load generated on a piston of a closed type electric compressor and provide a compressor the piston of which is miniaturized. SOLUTION: A head end part 21a of a piston 21 makes contact with a cylinder 9, and a protruded element 21c makes contact with an end part 22b of a sliding element 22. As the piston 21 receives a pushing load at this contact part, it becomes possible to increase a distance of two points on which the pushing load works in comparison with the case of receiving the pushing load only at a contact point with the cylinder, and consequently, it becomes possible to reduce the pushing load. |
