本発明は負圧応動装置のダイヤプラムに連接する部分の
結合構造に係り、特に配電器の真空進角装置に好適であ
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a connection structure of a portion connected to a diaphragm of a negative pressure response device, and is particularly suitable for a vacuum advance angle device of a power distributor.

As described in the 2010 publication, it is common to swage the shaft that fits into the diamond 7 and F, and for productivity, this shaft is either cut from free-cutting steel or is cold-forged. However, free-cutting steel has relatively little elongation, and cold-forged products are hard due to work hardening and cracks occur during tightening, causing problems with airtightness. Furthermore, when heat treating the shaft, partial hardening is required, which reduces productivity.
本発明の目的は、前述のかしめによるクラックまたは熱
処理の有無に関係のない品質、生産性の高い結合法を提
供するにある。An object of the present invention is to provide a bonding method with high quality and productivity regardless of cracks caused by caulking or the presence or absence of heat treatment.
本発明は、金属の塑性流動を応用し、弾性体を圧縮する
と同時に、該金属を軸に結合させるものである。The present invention utilizes the plastic flow of metal to compress an elastic body and simultaneously connect the metal to a shaft.

5bは圧縮ばね、6a。Hereinafter, an actual Mi example of the present invention will be explained with reference to FIGS. 1 and 2. A first negative pressure chamber 1a is composed of cases 2a, 3a and a diaphragm 4a. 1b is the second negative pressure chamber, case 2
b, 3b and a diaphragm 4b. 5a,
5b is a compression spring, 6a.
6bは連結軸でおる。7はU字状の継手、8はストッパ
である。9a、9bはピストン10a。6b is a connecting shaft. 7 is a U-shaped joint, and 8 is a stopper. 9a and 9b are pistons 10a.
10bは当板である。11は比較的歌い金属のワッシャ
、12a、12bは口金を示す。以上は公知の構造でる
る。10b is a contact plate. Reference numeral 11 indicates a relatively smooth metal washer, and 12a and 12b indicate caps. The above is a known structure.
13a、13bは連結軸5a、5bに設けたW状の溝で
、第2図に示す方法で、ワッシャ11、継手7を加圧し
、ダイヤフラム(一般に基布入り)4a、4bを圧縮す
ると同時に、該ワッシャ11、継手7の金属を、該溝6
a、6bに喰込ませて結合する。Reference numerals 13a and 13b are W-shaped grooves provided in the connecting shafts 5a and 5b, and at the same time, the washer 11 and the joint 7 are pressurized and the diaphragms (generally containing base fabric) 4a and 4b are compressed using the method shown in FIG. The washer 11 and the metal of the joint 7 are connected to the groove 6.
Insert into a and 6b and join.
次に他の実施例を第3図により説明する。例えば、ダイ
ヤフラム4aがゴムのみで基布が入っていないなどの場

するための段15を設ければよく、その効果は前記と同
一である。Next, another embodiment will be explained with reference to FIG. For example, if the diaphragm 4a is made of rubber and does not contain any base fabric, it is sufficient to provide the connecting shaft 6a with a step 15 for defining the compression margin of the diaphragm 4a, and the effect is the same as described above. .
本発明によれば、比較的歌い金属を、局部的に塑性流動
させるため、荷重を少なくしてダイヤフラムを圧縮する
と同時に重ね合せ部品の結合ができ、且つ、クラックの
発生もない特徴がある。According to the present invention, since the relatively sagging metal is locally made to plastically flow, the diaphragm can be compressed with a reduced load, and at the same time the overlapping parts can be joined, and there is no occurrence of cracks.
また、W溝に金属を喰込ませであるため、異種の金属の
組合せでも膨張、収縮に対し熱応力が発生し、結合部が
ゆるむことがない特徴がある。Furthermore, since the metal is bitten into the W groove, thermal stress is generated due to expansion and contraction even when different types of metals are combined, and the bonded portion does not come loose.
