装置。In an internal combustion engine in which a piston pin is press-fitted into a pin insertion hole at the small end of a connecting rod made of a material with a larger coefficient of thermal expansion than the piston pin, the cross-sectional shape of the pin insertion hole and the insertion of the piston pin into the pin insertion hole are disclosed. The cross-sectional shape of the piston pin is approximately oval, and the other is approximately a perfect circle, and the press-fitting allowance for the piston pin into the pin insertion hole in the direction approximately perpendicular to the axis of the connecting rod is maximized. Piston pin-connecting device for internal combustion engines.
