    • There is provided a seal device having a seal ring structure assemblable without lowering the assembling efficiency of CVT, and free from oil leakage when an oil pump is not operated with an engine stopped, namely when oil pressure is not applied to the seal ring, which comprises a combined seal ring comprising an endless resin ring having an outer peripheral surface in slidable contact with an inner peripheral surface of an outer member, and a coil expander pushing the resin ring toward its outer peripheral surface and side surface, the coil expander being arranged in a corner recess portion of the resin ring between its pressure-receiving side surface and its inner peripheral surface, and an inner peripheral side of the combined seal ring being separate from a bottom of the seal ring groove.
    • 提供一种密封装置,其具有可组装的密封环结构,而不会降低CVT的组装效率,并且当发动机停止时油泵不工作时,即,当没有油压施加到密封环时,没有漏油 包括:组合密封环,其包括具有与外部构件的内周表面可滑动接触的外周表面的环形树脂环和将所述树脂环朝向其外周表面和侧表面推动的螺旋胀圈,所述螺旋胀圈被布置 在其受压侧表面与其内周表面之间的树脂环的拐角凹陷部分中,并且组合密封环的内周侧与密封环凹槽的底部分离。
