この考案は、自動車のブレーキ装置を構成す
る、ホイールブレーキのシリンダーヘツドに被設
する、シリンダーブーツに関する。[Detailed Description of the Invention] This invention relates to a cylinder boot that is installed over the cylinder head of a wheel brake that constitutes a brake system for an automobile.
ホイールブレーキのシリンダーヘツドには、防
水や防塵のためブーツを被設する。 The cylinder head of the wheel brake is covered with a boot for waterproofing and dustproofing.
従来ブーツの被設は、シリンダー端縁近部の外
周壁に設けられた周溝に、合成樹脂材で形成した
ブーツの開口縁を、その材料の弾性を利用して、
嵌合することで行なわれていた。 Conventionally, the boot was installed by using the elasticity of the material by inserting the opening edge of the boot made of a synthetic resin material into a circumferential groove provided on the outer peripheral wall near the end edge of the cylinder.
This was done by fitting.
この嵌合の度合が緩いと、水または湿気の侵入

ける作業では、ブーツ開口縁が毀損してしまう問
題点があつた。 If the fit is too loose, it may allow water or moisture to enter and cause the inner surface of the cylinder to rust. If the fit is too tight, it will not only drastically reduce the efficiency of the boot fitting process, but also When working on the ground, there was a problem that the boot opening edge was damaged.
この考案は、この問題点を解決したブーツ開口
縁に金属製バンドを埋設して、ブーツを緩く被嵌
して作業能率を向上させると共に、ブーツの弾性
と金属製バンドの張力による締付力を相乗して、
タイトに締付けることができるホイールブレーキ
のシリンダーブーツを提供することを目的とする
ものである。 This idea solves this problem by embedding a metal band in the edge of the boot opening, allowing the boot to fit loosely and improving work efficiency, while also reducing the tightening force due to the elasticity of the boot and the tension of the metal band. Synergistically,
The object of the present invention is to provide a cylinder boot for a wheel brake that can be tightened tightly.
この考案を図示の実施例に基づいて詳細に説明
する。 This invention will be explained in detail based on illustrated embodiments.
第１図は一部を断面としたホイールブレーキの
シリンダーの平面図であるが、１がシリンダー本
体、２がシリンダーブーツである。 FIG. 1 is a partially sectional plan view of a wheel brake cylinder, in which 1 is a cylinder body and 2 is a cylinder boot.
シリンダーブーツ２は、合成樹脂材で形成し、

ケツト部２２を周設する。 The cylinder boot 2 is made of synthetic resin material,
The opening end edge of the outer periphery of the cylinder boot is formed into a thick fitting part 21, and as shown in FIG. To be established.
このポケツト部２２は、第３図に示すように、
シリンダーブーツ２の嵌合部２１の外周面に開口

Openings 23 and 24 opening on the outer peripheral surface of the fitting part 21 of the cylinder boot 2 are formed so as to be spaced apart at an appropriate distance.
つまり、一部を切欠いたドーナツ状に形成し、
切欠縁が開口部２３・２４に相当するように形成
する。 In other words, it is formed into a donut shape with a part cut out,
The notch edges are formed to correspond to the openings 23 and 24.

る。 On the other hand, as shown in FIG. 4, a thin plate band-like structure is formed by providing a bent part 31 near one end edge, and a biting part 32 formed by bending the end edge slightly spaced apart from the bent part 31. A metal band 3 is provided, the other smooth end of the metal band 3 is inserted through one opening 23 of the pocket 22 of the cylinder boot 2, the pocket 22 is run around, and the other smooth edge is inserted into the other opening. It is made to protrude from the portion 24. In this case, the bent end of the fitting part 32 is the fitting part 2 of the cylinder boot 2.
Insert it so that it is facing the outer circumferential surface of 1. Thereafter, the inserted smooth end portion is bent at a substantially right angle to the outer circumferential surface of the fitting portion 21 to stand up, thereby forming an overlapping portion 33 .

３を係合するように重ねる。 When using this cylinder boot 2, insert the cylinder boot 2 into the circumferential groove 11 provided on the outer circumferential wall near the opening end of the cylinder head of the cylinder body 1.
The fitting part 21 of the metal band 3 is fitted with an appropriate tension, and the biting part 32 and the overlapping part 3 of the metal band 3 are fitted.
3 so that they are engaged.
さらにその状態で、端縁が嵌合部２１の外周面

部１１に密接固定する。 Furthermore, in this state, the outer surface of the engaging part 32 whose end edge is facing the outer peripheral surface of the fitting part 21 is connected to the overlapping part 33.
The fitting part 21 is rotated while holding the fitting part 32 and the overlapping part 33 so as to press against the outer peripheral surface of the metal band 3 to which it is connected, thereby tightening the fitting part 21 and closely fixing it to the circumferential groove part 11 of the cylinder body 1.
この考案は上述の実施例に基づいて、実用新案
登録請求の範囲のように構成したので、シリンダ
ーブーツの被嵌作業が容易となり、特に寒冷地に
おける作業においても、シリンダーブーツの嵌合
部が損傷するようなことはない。 This invention is based on the above-mentioned embodiment and is constructed as claimed in the claims of the utility model registration, so that the work of fitting the cylinder boot is easy, and the fitting part of the cylinder boot can be easily damaged even when working in particularly cold regions. There's nothing to do.
またシリンダー本体との緊縮力はブーツの弾圧

ることができる。 Furthermore, since the tightening force with the cylinder body is based on the elastic force of the boot and the tension of the metal belt, the tightening force does not change much due to changes in temperature, and the tightening force can always be maintained within a certain range. Further, since the metal belt is provided with a bent portion, it is possible to alleviate local tightening force during fastening and apply uniform tightening force to the entire fitting portion.
また金属ベルトを嵌合部のポケツト内に巻設し
たので、金属ベルトの取付位置や「ずれ」に無関
係に作業を進めることができるので、取付作業の
能率を飛躍的に向上させることができた。 In addition, since the metal belt is wound inside the pocket of the mating part, work can proceed regardless of the installation position or "misalignment" of the metal belt, dramatically improving the efficiency of the installation work. .
