徴とするパツキング装置。 A lip portion protruding inward from the inner peripheral surface of the ring portion of the packing member is arranged so as to come into contact with the mating member, and when receiving frictional force from the mating member, the lip portion is arranged around the mating member. In a packing device that is capable of sliding along the sloped surface of the support ring, a recess is formed at the base of the lip portion so as to face the sloped surface of the support ring. A packing device characterized in that the lip portion is separated from the circumferential surface of the mating member during smooth sliding movement, thereby reducing friction between the lip portion and the mating member.
