いて、ピストンリングのすべり面は上方を、該リングの
背面は下方を、それぞれ境界線が直線又は任意の曲線状
に切り欠いたものとし、リングのすべり面の幅をＢとし
たとき、リングの背面の切り欠き幅をリング下方よりＢ
／２とすることを特徴とするピストンリング。In the cross-sectional shape of a piston ring of a reciprocating device such as an internal combustion engine, the sliding surface of the piston ring is cut out on the upper side, and the back side of the ring is cut out on the lower side, so that the boundary lines are straight or arbitrarily curved. When the width of the surface is B, the width of the notch on the back of the ring is B from the bottom of the ring.
A piston ring characterized by: /2.
