There is provided a reciprocal motion type compressor which has a piston reciprocally movable in a cylinder. The piston has a piston cover and a piston body portion. The piston cover has an insertion portion engaged with the piston body portion. The insertion portion has a sectional shape which becomes smaller gradually from the cover portion toward an end surface of the insertion portion.
