<p>PROBLEM TO BE SOLVED: To effectively lap a piston.SOLUTION: A piston lapping device includes a sleeve 1 which can reciprocate in a slide direction of a piston 3, and a load generating part for exerting a load on a piston pin 1a in the vicinity of the sleeve 1. The piston pin 1a and the load generating part are connected to each other by a frame 10. When an outer circumferential face of the piston 3 and an inner face of the sleeve 1 are slid on each other by reciprocating the sleeve 1, a load is applied to the piston pin 1a via the frame 10.</p> |
