封装置。[Claims for Utility Model Registration] An annular seal body fixed to the inner periphery of the housing is provided with a seal lip that extends toward the sealed fluid side and makes slidable and sealing contact with a movable shaft that is assembled concentrically to the housing. In a sealing device in which a back-up spring is interposed between the atmosphere-side side surface of the seal lip and the movable member, a rubber made of a rubber-like elastic body is provided in a sliding portion of the back-up spring that contacts the movable member in sealing contact with the movable member. A sealing device characterized in that a sliding member is provided, the seal lip is made of a heat-resistant material, and the rubber sliding member is made of a low-temperature-resistant material.
