【考案の詳細な説明】
本考案は自動車用および一般産業用の制御装置として使
用するディスクブレーキの改良、特に固定部材とキャリ
パとの支持部に使用する弾性体の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a disc brake used as a control device for automobiles and general industry, and particularly to an improvement in an elastic body used in a support portion between a fixed member and a caliper.
従来、固定部材に対しキャリパが弾性的に支持されてい
るディスクブレーキの一般構造は第１図で示すものであ
る。The general structure of a conventional disc brake in which a caliper is elastically supported by a fixed member is shown in FIG.
第１図において、支持部Ａはキャリパ１に設けられた貫
通穴１ａと、基端側か固定部材２に打込み等の手段によ
り固定的に嵌合され、先端側が貫通穴１ａ内に嵌合され
るように突出しているピン３と、前記貫通穴１ａとピン
３の先端側との嵌合面に組付けるため、先端部分を先に
して該貫通穴１ａに挿入されるゴム材等からなる弾性体
４とから構成されている。In FIG. 1, the support part A is fixedly fitted into the through hole 1a provided in the caliper 1 and the fixing member 2 at the proximal end by driving or other means, and the distal end is fitted into the through hole 1a. In order to assemble the pin 3 protruding as shown in FIG. It is composed of a body 4.
さらに、第１図において、５はピストン、６および７は
ディスク８をはさんで設けられているパッド、９はピス
トンシールである。Furthermore, in FIG. 1, 5 is a piston, 6 and 7 are pads provided on both sides of a disk 8, and 9 is a piston seal.
ところで、弾性体４の形状は、第２図で示すように円筒
袋形であり、さらにピン３の摺動に対し、組付部から脱
落しないように先端拡径部４ａの外径は中央部（キャリ
パ１に組込まれる部分）の外径より大きくなっている。By the way, the shape of the elastic body 4 is a cylindrical bag shape as shown in FIG. (the part incorporated into the caliper 1).
したがって、上述の形状を有する弾性体４をキャリパ１
の貫通穴１ａに組付ける場合は、弾性体４の先端拡径部
４ａを先にして貫通穴１ａの挿入口に押込む必要がある
ため、従来は挿入治具１０等により強引に押込んで組付
けを行なっていた。Therefore, the elastic body 4 having the above-mentioned shape is attached to the caliper 1.
When assembling into the through hole 1a of the elastic body 4, it is necessary to push the enlarged end portion 4a of the elastic body 4 into the insertion opening of the through hole 1a first. I was attaching it.
しかし、弾性体４の先端拡径部４ａは円形であるため貫
通穴径まで容易に収縮せず、押込み作業に必要以上の時
間と技術とを必要としていた。However, since the enlarged diameter end portion 4a of the elastic body 4 is circular, it does not easily contract to the diameter of the through hole, and the pushing operation requires more time and skill than necessary.
また、挿入治具１０により無理矢理押込むと弾性体４の
先端頂部４ｂが破損するなど弾性体４の組付に関しては
、多くの問題点があった。Further, there were many problems in assembling the elastic body 4, such as the top end portion 4b of the elastic body 4 being damaged if the insertion jig 10 was used to force the insertion jig 10 into the elastic body 4.
本考案は弾性体の形状を変えることにより上述したよう
な弾性体の組付上の問題点を解決させたディスクブレー
キを提供することを目的とするものである。The object of the present invention is to provide a disc brake that solves the above-mentioned problems in assembling the elastic body by changing the shape of the elastic body.
上記目的を達成するために、本考案が採用する構成の特
徴は、弾性体の挿入側先端部分には挿入側先端より徐々
に拡径される先端拡径部を設け、該先端拡径部の外周面
側には１個所以上の切欠部を設けたことにある。In order to achieve the above object, the feature of the configuration adopted by the present invention is that the insertion-side distal end portion of the elastic body is provided with a distal enlarged diameter portion whose diameter gradually increases from the insertion side distal end, and the distal enlarged diameter portion is The reason is that one or more notches are provided on the outer peripheral surface side.
以下、本考案について第３図ないし第６図に示す実施例
により説明する。The present invention will be explained below with reference to embodiments shown in FIGS. 3 to 6.
第３図ないし第５図は本考案の第１の実施例を示し、本
実施例に用いる弾性体４′は第３図に示す如く、該弾性
体４′の挿入側先端部分には先端頂部４’ｂより徐々に
拡径される先端拡径部４’ａを設け、該先端拡径部４’
ａの外周側面の一部を中央部（キャリパ１に組込まれる
部分）の外径とほぼ同一径に切り落した切欠部４’Ｃを
設けたことを特徴とするものである。3 to 5 show a first embodiment of the present invention, and the elastic body 4' used in this embodiment has a top end at the insertion side distal end portion of the elastic body 4' as shown in FIG. A tip enlarged diameter section 4'a whose diameter gradually increases from 4'b is provided, and the tip enlarged diameter section 4'
It is characterized by providing a notch 4'C in which a part of the outer circumferential side surface of a is cut off to have approximately the same diameter as the outer diameter of the central portion (the portion to be incorporated into the caliper 1).
上述したような切欠部４’Ｃを設けた弾性体４′をキャ
リパ１の貫通穴１ａに組付ける場合には弾性体４′の先
端拡径部４’ａの外径は貫通穴１ａの内径にガイドされ
内側に収縮しようとする。When assembling the elastic body 4' provided with the notch 4'C as described above into the through hole 1a of the caliper 1, the outer diameter of the enlarged diameter portion 4'a at the tip of the elastic body 4' is equal to the inner diameter of the through hole 1a. It is guided by and tries to contract inward.
この収縮しようとする力は先端拡径部４’ａ中で最も強
度の弱い部分である切欠部４’Ｃに集中してかかるため
、先端拡径部４’ａは第４図に示すように切欠部４’Ｃ
および首部４’ｄが折れ込んだ状態となる。This shrinking force is concentrated on the notch 4'C, which is the weakest part of the enlarged tip portion 4'a, so that the enlarged tip portion 4'a becomes as shown in FIG. Notch 4'C
And the neck portion 4'd is in a folded state.
したがって、組付時において挿入治具１０等により強引
に押し込まなくとも弾性体４′は容易に組込むことがで
きる。Therefore, the elastic body 4' can be easily assembled without being forced into it using the insertion jig 10 or the like during assembly.
第６図は他の実施例を示すもので、弾性体４″に左右２
ケ所の切欠部４″Ｃを設けた場合の組付状態を示したも
のであり、弾性体４″をこのような形状にすることによ
り、より容易に組付けることができる。Fig. 6 shows another embodiment, in which there are 2 left and right parts on the elastic body 4''.
This figure shows an assembled state in the case where notches 4''C are provided at several locations.By forming the elastic body 4'' into such a shape, it can be more easily assembled.
なお、本考案の実施例においては、支持部の構成がキャ

レーキにも適用できることは勿論である。In addition, in the embodiment of the present invention, the structure of the support part is described as an elastic body of a disc brake having a structure in which the caliper has a through hole and the fixing member has a pin. Needless to say, the present invention can also be applied to a disc brake having a structure with a through hole.
また、キャリパが固定部材に対して摺動しないタイプの
ディスクブレーキにも適用できる。Furthermore, the present invention can also be applied to a type of disc brake in which the caliper does not slide against a fixed member.
本考案は以上詳細に述べた如く、弾性体の先端拡径部に
