Claims

[Scope of utility model registration request]

A first radial end 2 extending radially from the first cylindrical part 1 is made of a rubber-like elastic material and has a substantially truncated conical shape, axially opposite the first cylindrical part 1. a first sealing member 5 integrally formed with a first sealing lip 3 extending in a direction and having a shallow ventilation groove 4 disposed on a circumferential surface running substantially in an axial direction; A second radial part 7, which extends radially from a second cylindrical part 6 facing the part 1 and faces the first radial part 2, is made of a rubber-like elastic material and has a shaft. A second seal member 10 is formed by integrally joining a plurality of pieces of second seal lips 9 arranged in parallel in the direction, and the first seal lip 3 is in elastic contact with the circumferential surface of the second cylindrical portion 6. At the same time, the second seal lip 9 is bent in the opposite direction to the second cylindrical portion 6 and assembled so as to come into elastic contact with the circumferential surface of the first cylindrical portion 1.
