密封装置。 The packing made of a rubber-like elastic material is composed of a lip part on the inner diameter side that closely slides on the shaft, and a base part on the outer diameter side that has a tapered surface that gradually becomes thinner toward the end and extends in the axial direction. The entire base is pressed and clamped so as to be held by the inner surface of a circumferential groove formed on the inner circumferential surface of the housing, the outer diameter side of which corresponds to the base and expands in a dovetail groove shape in the axial direction. Sealing device.
