Abstract

PURPOSE:To prevent a piston from being deformed or cradked by making the entire outer circumferential part of a piston in which the samll spherical part of a connecting rod is inserted and supported, into a smooth cylindrical surface. CONSTITUTION:Hill-shaped projection 4 is provided on the position of the outer circumferential part of piston 3 corresponding to fitting part 2a of small spherical part 2 of connecting rod 1. Next, small spherical part 2 of connecting rod 1 is inserted into inner part 3a of piston 3, and projection 4 is made into a smooth cylindrical surface of the height same as the outer circumferential part of the piston. By this, the inner surface of piston 3 corresponding to fitting part 2a of small spherical part 2 of connecting rod 1 can be made to project in a hill shape and thereby small spherical part 2 of connecting rod 1 can be inserted in and hold by piston 3.
