Reference numeral 6 denotes a connecting rod having a small end 8 at one end provided with a through hole inserted into the hollow portion 2 and through which the piston pin 4 passes, and a large end connected to a drive device (not shown) or the like at the other end. It has part 9. 10 is U-shaped and each has a piston pin through hole 11 at its free end.

い。In the above configuration, the piston 1 and the connecting rod 6 are connected as follows. First, place U in the hollow part 2 of the piston 1.
The washer 10 and the small end 8 of the connecting rod 6 are inserted, respectively, and the through holes 3 and 13 of the piston 1, the piston through hole 11, and the through hole 7 are aligned. Then, the piston pin 4 is inserted into the through hole 3, the through hole 7, and the through hole 13, respectively. At this time, the protrusion 12 of the U washer 10 and the locking groove 6 of the piston pin 4 are engaged, stopping the rotation of both, and furthermore, the contact between the top surface 5a of the locking groove and the protrusion 12 prevents it from falling. Prevented. Therefore, in supporting the piston pin 4, assembly is simple and the piston pin 4 is not damaged. Furthermore, since the locking groove 5 of the piston 4 is aligned with the sliding direction of the piston 1, elastic deformation of the piston 4 is reduced.
