Abstract: PROBLEM TO BE SOLVED: To improve tensile strength of piston structure by making an insertion part section shape fitted to a piston body part of a piston cover a shape gradually decreasing in its area from the cover to an end face of insertion part. SOLUTION: A piston 100 is composed of a body 101 and a cover 102. A connection part 105 between the cover 102 and a body 101 outer side is formed so that the sectional form of an insertion part 103 extending from the cover 102 is in the direction where it is inserted into the body part 101 gradually, namely so that it is decreased gradually toward the insertion end face. With the shape of insertion part 103, when the insertion part 103 is applied with shock, it extends to the body part 101 and is brought into close contact therewith to generate a strong close contact characteristic and a suction force. Accordingly, with the insertion part shaped in this way, the tensile strength of piston structure can be increased without increasing the thickness as a whole.
