摘要： A valve stem seal device has a valve stem guide, a cylindrical metallic ring retained to an outer periphery of the valve stem guide, a rubbery elastic seal lip integrally formed in one end side of the metallic ring, and hermetically sliding to the valve stem, and a valve stem seal having the cylindrical metallic ring and the seal lip and fixed to the valve stem guide side. The valve stem seal device has a stop ring retained between a circular-truncated-cone-shaped surface which is expanded toward a side of the seal lip formed in an outer peripheral surface of the valve stem guide, and a cylindrical inner peripheral surface of the metallic ring. The stop ring has a cut part, and a movement limiting means for limiting a movement in an axial direction of the stop ring is provided in the other end side of the metallic ring.

摘要： A sealing device comprises an annular first seal member composed of a rubber-like elastic member and a metal ring member for reinforcement and an annular second seal member composed of a sliding member formed of a resin material and a rubber-like elastic member. The first seal member is provided with a seal lip extending towards a fluid side to be sealed and slidably contacting, in a sealed manner, an objective rotational shaft which is slidable relative to the seal lip, and the first seal member is also with provided an annular recessed portion, formed to an end surface of the first seal member on a side opposite to the fluid side, to which the second seal member is fitted. The second seal member has an endless shape. An outer peripheral portion of the elastic member of the second seal member is engaged with an inner peripheral wall of the annular recessed portion of the first seal member, and the sliding member of the second seal member slidably contact, in a sealed manner, the rotational shaft.
