問題となつている。 As a prior art related to the present invention, there is one shown in FIG. 1. FIG. 1 is a sectional view of an oil seal 50 made of a rubber-like elastic material in which a reinforcing ring 54 is embedded, and an outer circumferential surface 52 of the oil seal 50 is made of a rubber material. The outer circumferential surface 52 is fitted onto the inner circumferential surface 56 of the housing 55, and a stopper 53 provided on the opening side of the housing prevents the oil seal 50 from coming off.
In another prior art, one end of a cylindrical housing is bent instead of a stopper to prevent the oil seal 51 from coming off.
However, depending on the installation location of the oil seal, it may be difficult to install these stoppers 53, or it may be difficult to bend one end of the housing.
It's becoming a problem.
本考案は上述のような問題点に鑑みなされたも
のであつて、その目的は、シール装置の取付が容
易にできると共に、確実に係合固着させることに
ある。 The present invention was devised in view of the above-mentioned problems, and its purpose is to facilitate the installation of a sealing device and to securely engage and secure the sealing device.
上述の課題解決のため、本考案は以下のように
構成されている。 In order to solve the above problems, the present invention is configured as follows.
ゴム状弾性材製の円筒状の取付部に円筒部を有

の凹部に係止させることができるから、確実に固
着することができる。 Since the reinforcing ring has a slit in its cylindrical portion, the cylindrical portion of the reinforcing ring can be deformed in the radial direction. Therefore, it can be easily inserted into the mating mounting circumferential surface, and the engaging protrusion can be locked in the recessed portion of the mating mounting circumferential surface, so that it can be securely fixed.
以下、本考案の一実施例を図面に基いて詳細に
説明する。 Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

１３に沿つて係合突起４が設けられている。 FIG. 2 is a sectional view of an oil seal belonging to the seal device. The reinforcing ring 1 made of a metal material is formed into an annular body having an L-shaped cross section. A slit 3 is provided halfway in the axial direction of this cylindrical portion 2, and
An engaging protrusion 4 is provided along the circumferential surface 13 of the cylindrical portion 2 on the side where the slit 3 is provided.
そして、補強環１の係合突起４が設けられてい
る反対周面にはゴム状弾性材製の円筒状をした基
部５が一体に接合されて取付部１２を成すと共
に、取付部１２から伸びるシールリツプ６を有し
てシール装置１０を構成している。更に、補強環
１の径方向部８の自由端側にはゴム状弾性材のシ
ール部７が形成されている。 A cylindrical base portion 5 made of a rubber-like elastic material is integrally joined to the opposite circumferential surface of the reinforcing ring 1 on which the engagement protrusion 4 is provided, forming a mounting portion 12 and extending from the mounting portion 12. A seal device 10 includes a seal lip 6. Further, a seal portion 7 made of a rubber-like elastic material is formed on the free end side of the radial portion 8 of the reinforcing ring 1.
上述の構成は本考案の一実施態様であるが、補
強環１は金属材の他に樹脂材、又は基部５より硬
質のゴム材に構成することができる。 Although the above-described structure is one embodiment of the present invention, the reinforcing ring 1 may be made of a resin material or a rubber material harder than the base 5 in addition to the metal material.
上述のように構成された本考案は以下のような
効果を奏する。 The present invention configured as described above has the following effects.
第３図は本考案のシール装置の嵌着状態の断面

ング９の凹部１１に係止させる。 FIG. 3 is a cross-sectional view of the sealing device of the present invention in a fitted state, in which the slit 3 side of the cylindrical portion 2 of the mounting portion 12 is expanded in the outer radial direction and fitted onto the outer circumferential surface of the housing 9, and The engagement protrusion 4 is locked in the recess 11 of the housing 9 by the elastic restoring force of the portion 2 or by the elastic force of the cylindrical base 5.
その結果、シール装置１０をハウジング９に嵌
合させることは極めて容易であり、更に、係合突
起４と凹部１１とは、シール装置１０が離脱しな
いように係止するから、シール装置１０の装着は
確実である。 As a result, it is extremely easy to fit the sealing device 10 into the housing 9, and furthermore, since the engaging protrusion 4 and the recess 11 are engaged so that the sealing device 10 does not come off, the sealing device 10 can be attached easily. is certain.
しかも、シール部７がハウジング９に密接して
いるから嵌合面のシールは更に確実である。 Moreover, since the seal portion 7 is in close contact with the housing 9, the sealing of the fitting surface is even more reliable.
また、金属材製補強環が相手部材の凹部と係合
するため、ゴム状弾性材製の係合突起に比べ係合
が確実に行なえるものである。 Further, since the reinforcing ring made of a metal material engages with the recess of the mating member, engagement can be performed more reliably than with an engagement protrusion made of a rubber-like elastic material.
