<p>PROBLEM TO BE SOLVED: To secure rigidity of a connecting part to link a linking part on the driving mechanism side with a piston body, and also to lighten it. SOLUTION: In a compressor piston 18 having the hollow piston body 18A sliding in a cylinder bore 3, a linking part 18B linked with the driving mechanism, and a connecting part 18C to link them, a conical surface 18J is formed on the inside wall of the connecting part 18C. Thereby, rigidity of the connecting part 18C is greatly increased, and vibration of the compressor is prevented, since the piston 18 is lightened by forming the connecting part 18C into a thin one.</p> |
