。 A piston pin for an internal combustion engine in which both ends are rotatably fitted to the pin boss part of the piston and a small end of a connecting rod is connected to the center part. The cross-sectional shape near the boundary between the fitting part and the connecting rod fitting part has a larger moment of inertia with respect to an axis perpendicular to the axial direction of the piston than the second moment of inertia with respect to an axis along the axial direction of the piston. A piston pin for an internal combustion engine, characterized in that it has a different shape and is provided with an engaging portion that engages with the piston side so as to restrict the rotation angle of the piston pin to approximately the same range as the connecting rod rocking angle. .
