ることを特徴とする密封装置。 An annular valve seat member that rotates as a result of the shaft and is movable relative to it in the axial direction is hermetically fitted onto the outer periphery of the shaft inserted into the shaft hole of the casing, so that the outer diameter surface of the valve seat member and the A non-contact type seal is formed between the inner wall surfaces of the shaft hole, and a contact type seal is connected to the non-contact type seal, and a weighted rubber band or the like is installed between the outer peripheral surface of the shaft and the valve seat member. A sealing device characterized in that a valve seat member movement control means moves the valve seat member in the axial direction when the shaft rotates at a constant speed to release the sealing operation of the contact type seal.
