Claims

[Scope of utility model registration request]

One or more gaskets are fitted into the gap between the relatively moving shaft and the hole in the housing and are clamped by adapters 21 and 22 from both sides in the axial direction, and the gaskets are connected to the inner circumferential lip 25 and the outer circumferential lip 24. A concave surface 28 and a convex surface 29 are formed on both sides in the axial direction so as to form a V-shaped cross section, and a convex periphery protruding from the concave surface 28 or convex surface 29 on the concave surface 28 or convex surface 29 of the sliding side lip of the packing. A surface portion 31 is provided,
The packing is made such that the packing and the adapter are overlapped to form an annular gap 30 on the side of the overlapped concave surface 28 or convex surface 29 of the non-sliding side lip.
