    • Provided is a seal ring that has low-leakage characteristics and low-friction characteristics and can improve the drive loss of the automatic transmission of an automobile to thereby contribute to an improvement in the fuel consumption of the automobile. The seal ring is attached to a shaft groove formed on the outer peripheral surface of a shaft. A plurality of peripherally spaced recessed sections are formed on at least the inner peripheral side of a contact side-surface. Inner walls are provided on the inner peripheral side of the recessed sections, and oil introduction openings that open on an inner peripheral surface are provided on the inner peripheral side of the recessed sections. The inner walls may be provided on opposite peripheral sides of the recessed sections but may be provided only on the rear side in the rotation direction.
    • 具有低泄漏特性和低摩擦特性的密封环,能够提高汽车的自动变速器的驱动损失,有助于提高汽车的燃料消耗。 密封环附接到形成在轴的外周表面上的轴槽。 在接触侧面的至少内周侧形成有多个周向间隔开的凹部。 在所述凹部的内周侧设置有内壁,在所述凹部的内周侧设置有在内周面开口的导油孔。 内壁可以设置在凹部的相对的周边上,但是也可以仅设置在旋转方向的后侧。
