ルは平担パツキンに形成される構造になっているのであ
る。(Prior Art) The above-mentioned breather device is constructed by screwing a breather plug having a ventilation hole into the casing with a seal interposed on the joint surface with the casing side. Although it is common, in the conventional one, as shown in Fig. 4, the end face of the breather hole drilled in the breather plug is exposed outward, and there is an intervening space between the joint surfaces. The seal is formed on a flat packing.
したがって従来構造のものでは機械を水洗する際などに
、ブリーザ−穴が外部に露出開口している故にその開口

ブリーザ−栓蓋脱時の締付けの繰返しによって外部には
み出したり、疲労による変形や破損で充分にシール効果
が遂されなくなるといった問題が起っている。Therefore, with the conventional structure, when washing the machine with water, the breather hole is exposed to the outside, so water can easily enter the casing through the opening, causing various problems with the internal housing mechanism (for example, clutch In the storage case, water intrusion causes the clutch plate to rust and become stuck, making it impossible to shut off.)
In addition, since the seal is simply a flat material, it may protrude from the outside due to repeated tightening when the breather cap is removed, or it may become deformed or damaged due to fatigue, resulting in problems such as insufficient sealing effect. ing.

設している。Reference numeral 4 denotes a breather plug, which is integrally formed from a mounting part 4a having a male thread that is screwed into the female thread 3, and a lid part 4b. 2 top surface 2a
Furthermore, a breather hole 4e is formed at an appropriate position in the lid 4b to communicate the cavity 4C with the outside in a direction different from the mounting direction A of the breather plug 4.
７はブリーザ−栓を取付けるに際し、段部下面６と取付
部上面２ａ間に介在挟着させるシールであり、このシー
ル７の外縁部には蓋部４ｂの段部側面８との間に適宜の
隙間を保って立ち上りブリーザ−穴４ｅの開口外側部を
、ブリーザ−作用の可能な状態で遮へいする耳部７ａを
有せしめているものである。Reference numeral 7 denotes a seal that is interposed and sandwiched between the lower surface 6 of the step and the upper surface 2a of the mounting portion when the breather plug is installed, and the outer edge of this seal 7 has an appropriate seal between it and the side surface 8 of the step of the lid portion 4b. It has an ear portion 7a which stands up while maintaining a gap and shields the opening outer side of the breather hole 4e in a state where the breather action is possible.
第２図は変形例を示すもので、はとんどの構成は第１図
の場合と同様であるが、ブリーザ−栓の蓋部４ｂにおけ
る段部上側部位Ａを、第１図のものに比して周囲へ大き
く張り出させて形成しているものである。FIG. 2 shows a modified example. Most of the structure is the same as that shown in FIG. It is formed by extending it out to the surrounding area.
また、第３図も変形例であって、この場合も主要構成は
第１図のものと同様であるが、ブリーザ−栓における蓋
部４ｂへ溝Ｂを設け、この溝Ｂにシール耳部７ａが適宜
の隙間をもって入り込むように形成しているものである
。Further, FIG. 3 is also a modified example, and in this case as well, the main structure is the same as that in FIG. It is formed so that it enters with an appropriate gap.
尚、第４図は従来装置を示すもので、１′はケーシング
、２′は取付部、４′はブリーザ−栓、７′はシールで
ある。FIG. 4 shows a conventional device, in which 1' is a casing, 2' is a mounting portion, 4' is a breather plug, and 7' is a seal.
このような構成のものでは、シール７を介在させた状態
で、ブリーザ−栓４を取付部２に螺合させて締付ければ
、シール７が栓の段部下面６と取付部上面２ａとの間の
気密を保つとともに、シール耳部７ａがブリーザ−穴４
ｅの外側部にあってブリーザ−作用は可能なように穴外
側部を覆うのである。With such a configuration, when the breather plug 4 is screwed onto the mounting portion 2 and tightened with the seal 7 interposed, the seal 7 connects the stepped lower surface 6 of the plug and the upper surface 2a of the mounting portion. While maintaining airtightness between the seal ears 7a and the breather holes 4,
The breather action is possible on the outer side of e and covers the outer side of the hole.
したがって、ケーシング１またはケーシングが組込まれ
た機械全体を水洗清掃するような場合にも、前述耳部７
ａがブリーザ−穴４ｅに侵入しようとする水を遮ぎるの
で、ケーシング内部に水を不測に入れることが自動的に
阻止でき、不具合の発生を防止できるのである。Therefore, even when cleaning the casing 1 or the entire machine in which the casing is incorporated, the ear portion 7
Since the portion a blocks water from entering the breather hole 4e, it is possible to automatically prevent water from entering the casing unexpectedly, thereby preventing the occurrence of malfunctions.
（効 果）
本考案は、ブリーザ−栓４と取付部２との対応面間に介
装するシール７の外周縁部から耳部７を一体に立ち上ら
せて形成しているから、その耳部７がブリーザ−栓締込
み時に押圧されるシールの異常変形を補強阻止し良好に
対応面間のシール作用を行わせ得る。(Effects) In the present invention, the ears 7 are integrally formed upright from the outer peripheral edge of the seal 7 interposed between the corresponding surfaces of the breather plug 4 and the mounting portion 2. The ear part 7 can reinforce and prevent abnormal deformation of the seal pressed when the breather plug is tightened, and can perform a good sealing action between the corresponding surfaces.
しかも、立ち上り耳部７はシール７の外周縁全体に設け
られるので、ブリーザ−栓がどの回転位置になっても必
ずブリーザ−栓のブリーザ−穴４ｅの開口外側部を遮へ
いして外部からの水の侵入を確実に防止できる。In addition, since the raised ear portion 7 is provided on the entire outer periphery of the seal 7, no matter what rotational position the breather plug is in, it always shields the outside opening of the breather hole 4e of the breather plug and prevents water from entering from outside. It is possible to reliably prevent the intrusion of
しかもシール材を一部改めるのみで上記を可能にするの
で、従来に比しても構造がほとんど複雑とならず製作、
取扱いは容易であるといった効果を奏するものである。Moreover, since the above can be achieved by only partially modifying the sealing material, the structure can be manufactured with almost no complexity compared to conventional methods.
This has the effect of being easy to handle.
