With respect to the center axis of the first and second pin holes for supporting the piston pin, the first and second thinnest portions of the piston head are respectively provided on both sides of a transverse axis that is perpendicular to the center axis of the first and second pin holes. Each of first and second rib portions that are respectively formed on inner surfaces of first and second pin boss portions extends at the piston head in a direction along the transverse axis to overlap each of the first and second thinnest portions of the piston head.
