摺動させて密封機能を果たすものである。 In order to prevent leakage of fluid passing between a stationary member and a moving member that are concentrically combined with each other, the first oil seal is disposed between the two members.
As shown in the figure, a holding part 1 made of a rubber-like elastic material and having a substantially cylindrical shape, a supporting part 3 extending radially from the end of the holding part 1, and a supporting part formed into a substantially cylindrical shape. The holding part 3 is attached to a stationary member, and the lip part 2 slides on the circumferential surface of a moving member to perform a sealing function. .

大であつた。 In the above-mentioned conventional oil seal, the width of the holding part 1 is usually set to be significantly narrower than the diameter of the holding part 1, so when it is mounted on a stationary member, it tilts and loses its sealing function. There was a great risk that the service life would be shortened due to deterioration and abnormal wear of the sliding parts.

を設けた構成となすものである。 In consideration of the problems with the conventional oil seals described above, the present invention provides a conical surface that corresponds to the chamfer formed at the open end of the stationary member at one end of the holder that is attached to the stationary member. A mounting guide lip having a larger diameter end portion larger than the outer diameter of the holding portion is provided, and an annular accommodation groove is provided in a portion of the holding portion adjacent to the mounting guide lip. This is what is done.

が形成されている。 The embodiment shown in FIG. 2 consists of a holding part 1 attached to a stationary member 6, a lip part 2 into which a moving member 7 is slidably inserted, and a support part 3 connecting the holding part 1 and the lip part 2. A reinforcing ring 8 made of a plate material and made into an annular body having a substantially L-shaped cross section is embedded inside the holding part 1 and the supporting part 3, and a chamfer is formed at the open end of the stationary member 6. The attachment guide lip 4 is provided with a conical surface corresponding to the holding part 1, and the diameter of the large diameter end is set to be larger than the outer diameter of the holding part 1.
is integrally attached to the outside of the support part 3, and is attached to a portion of the outer periphery of the holding part 1 adjacent to the mounting guide lip 4.
An annular accommodation groove 5 capable of accommodating the mounting guide lip 4
is formed.

As shown in FIG. 3, when the stationary member 6 is inserted into the opening of the stationary member 6, it comes into elastic contact with the chamfered portion formed at the opening end, and the holding portion 1 guide the insertion of the fourth
As shown in the figure, it is deformed by being pressed against the inner circumferential surface of the opening, and is housed in the annular housing groove 5 .

Since it comes into close contact with the inclined surface of the chamfer formed at the open end of the stationary member, the insertion of the holding part into the stationary member is accurately guided, and therefore the oil seal is installed normally, resulting in stable sealing. Functionality is maintained, and abnormal wear of the sliding parts does not occur, resulting in a longer service life.
