    Abstract: The sealing device includes: an outer peripheral ring 2000 that is in contact with a side wall surface of an annular groove 4100 at a low pressure side (L), and slides with respect to an inner peripheral surface of a shaft hole in a housing 5000 through which a shaft 4000 is inserted. An inner peripheral ring 3000 made of a rubber-like elastic body that is in contact with an inner peripheral surface of the outer peripheral ring 2000 and a groove bottom surface of the annular groove 4100, respectively. The outer peripheral ring 2000 is formed on its outer peripheral surface with a concave portion 2220 which extends from an end of a high pressure side (H) to a position which does not arrive at an end of a low pressure side, so as to introduce fluid thereinto from the high pressure side.

    Abstract translation: 密封装置包括：外周环2000，其与低压侧（L）的环状槽4100的侧壁面接触，并且相对于壳体5000中的轴孔的内周面滑动 轴4000插入其中。 由与外周环2000的内周面接触的橡胶状弹性体和环状槽4100的槽底面分别形成的内周环3000。 外周环2000在其外周面形成有从高压侧（H）的端部延伸到未到达低压侧的端部的位置的凹部2220，以便引入 来自高压侧的流体。
