Claims

[Scope of utility model registration request]

In the structure of an engine piston/conrod in which a piston that reciprocates in a cylinder is swingably connected to a connecting rod by a piston pin, the explosion pressure receiving side of the pin bearing of the rod is closer to the ash receiving pressure side. A position formed to be wide along the axial direction of the piston pin, where the explosion pressure receiving side of the pin bearing of the piston is wider than the ash pressure receiving side and partially faces the explosion pressure receiving side of the connecting rod. A structure of a piston/connecting rod, characterized in that a gap is provided in the circumferential direction of the piston pin, the gap being formed so as to extend into the interior of the piston, and allowing the connecting rod to swing at the opposing positions of both pressure receiving side parts.
