Claims

[Scope of utility model registration request]

A sealing device that seals between a shift rod 15 penetrating a shift rod insertion hole 2 in a casing 1 filled with lubricating oil, and a mounting hole 4 having a stepped portion 3' is formed in the shift rod insertion hole 2. However, the outer peripheral surface 7 that fits into the mounting hole 4 is formed to have a slightly smaller diameter than the inner diameter of the mounting hole 4,
The boot 5 is provided with a mounting portion 6 made of an annular rubber-like elastic material at one end and having end surfaces 8, 8 formed at both ends of the outer circumferential surface 7 which is longer than the mounting hole 4 in the axial direction. The mounting portions 6 are fitted into the mounting holes 4 and both end faces 9. , 9 is a holding plate 13 that holds the stepped portion 3 and the mounting portion 6! The sealing device is supported so that an intermediate portion 14 on the side of the outer circumferential surface 7 expands in the outer radial direction and is in close contact with the inner circumferential surface of the mounting hole 4.
