ならない問題を有するのが現状である。 As a prior art related to the present invention, there is an oil seal shown in FIG. The oil seal 50
are a fitting part 52 and a shaft 53 that fit into the housing 51.
and a sealing lip 54 which is a sealing fit. If the diameter of the fitting hole 55 of the housing 51 into which the fitting portion 52 of the oil seal 50 fits is somewhat larger than that of the fitting hole 55, or if the circumferential surface of the fitting hole 55 is rougher than necessary due to processing, The fitting portion 52 of the oil seal 50 cannot be fitted into the mounting hole 55. For this reason, the current situation is that a wide variety of oil seals 50 suitable for each mounting hole 55 must be manufactured.
本考案は上述のような問題点に鑑み成されたも
のであつて、その技術的課題はシールの嵌合部が

着できるようにすることにある。 The present invention was developed in view of the above-mentioned problems, and the technical problem is that even if the fitting part of the seal does not fit the mounting dimensions of the member to be fitted, The objective is to make the parts compatible so that they can be easily fitted.
本考案は上述の技術的課題を解決するために、
下記する技術的手段によつて構成する。 In order to solve the above-mentioned technical problems, this invention
It is constructed by the following technical means.

A seal having a seal lip made of an elastic material and bonded to the fitting portion to make elastic contact with the other circumferential surface of the two members, wherein a rubber-like elastic material is applied to the circumferential surface of the fitting portion. A plurality of deformable protrusions are provided which extend in the axial direction as well as in the radial direction and come into elastic contact with the circumferential surface of the one member; An annular seal portion is attached to the portion to make elastic contact with a radial surface formed on the one member.
上述のように構成された本考案は以下のような
特有の効果を奏する。 The present invention configured as described above has the following unique effects.

る。 Since the fitting part of the seal is provided with multiple protrusions made of rubber-like elastic material, even if the mounting hole of one member has a smaller diameter than the fitting part, it will not be difficult to insert the fitting part. The fitting portion can be elastically deformed and fitted into the mounting hole. Therefore, even if the dimensions of the mounting hole do not correspond to the fitting part of the seal, that is, the dimensions of the mounting hole are formed so that other seals of similar dimensions will fit, the seal of the present invention can be fitted. can do. As a result, even if there is no seal with a size corresponding to the mounting hole, it can be easily installed by using the seal of the present invention, and the number of types of seals according to the size of the fitting part can be reduced. This makes it possible to standardize each type of seal. The sealing performance at the joint between one of the two concentrically assembled members and the fitting part is determined by the elastic contact of the seal part attached to the end of the fitting part with the radial surface formed on one member. It is held by twisting.

A fitting part 2 is formed on the outer circumferential side of the seal 1, and a plurality of convex parts 3 made of a rubber-like elastic material and extending in the radial direction as well as along the axial direction are formed on the outer periphery of the fitting part 2. are arranged in equal parts. The convex portion 3 has a trapezoidal cross section in the outer diameter direction. Further, it has a side surface portion 5 extending in the radial direction from one end of the fitting portion 2, and a seal portion 6 is provided on the side surface portion 5. Further, a sealing lip 4 is provided on the inner peripheral side of the fitting part 2, and this sealing lip 4 has a sealing part 7 and is closely fitted to the shaft 53. Reinforcement rings 9 and 10 are embedded in the fitting part 2 and the side part 5 to reinforce the fitting part 2 and the side part 5 so that they do not lose their functions.

保持している。 By configuring as described above, the seal of the present invention can be installed without requiring a matching seal even if the fitting dimensions of one of the two members that are fitted relative to each other are different. can. Furthermore, even if the two members are somewhat eccentric relative to each other, the convex portion 3 of the fitting portion of the present invention allows the sealing portion 7 of the seal lip 4 and the other member, which is the shaft, to be in close contact with each other. It can be elastically adapted to fit. Moreover, on the fitting part 2 side, the seal part 6 is in close contact with one member, which is the housing, to reliably maintain the seal.
