封装置。 A sealing member is provided that divides the inside of the housing into a sealed fluid side and a guide member side by contacting its tip along the outer peripheral surface of a movable shaft that is slidably supported by a guide member, and In a sealing device in which sealing fluid can be supplied to the guide member side when the movable shaft is operated by forming a slope that maintains a predetermined inclination angle toward the shaft,
A reversible expandable body is installed between the tip of the sealing member and the guide member to absorb sealing fluid and expand to press the tip of the sealing member in the axial direction. A sealing device that adjusts the amount of sealing fluid supplied by varying the inclination angle of the tip due to contraction.
