スカート内部よりピストン外周面の方向に設け、
しかもピストンピン孔の端縁内周面にはオイル溝
のない平滑な壁面部を形成してなることを特徴と
するピストンピン孔潤滑構造。 An oil groove is provided on the inner peripheral surface of the piston pin hole from the inside of the piston skirt toward the outer peripheral surface of the piston.
Moreover, the piston pin hole lubrication structure is characterized in that the inner circumferential surface of the end edge of the piston pin hole is formed with a smooth wall surface having no oil groove.
