<p>The present invention provides a compressor piston which can make the strength of the engagement of the piston be stable. The compressor piston is formed by the following members: a piston body and a piston cap. The piston body is formed by a connection part connected with a drive unit of the compressor and a joint part which is formed together with the connection part in a whole. The piston cap is bottomed cylindrical. One side of the piston body is provided with an opening used for connecting with the piston body. The abut wall for the connection part of the piston body is abutted with the end wall of the circumferential wall opening of the piston cap. Under the condition of the outer circumferential surface of the connection part facing the inner circumferential surface of the circumferential wall, the end wall is connected with the abut wall. A groove portion is disposed on one circumferential surface of the outer circumferential surface of the connection part and the inner circumferential surface of the circumferential wall.</p> |
