Description

【考案の詳細な説明】この考案は、オートバイ等の小型エンジン始動レバーの
戻りスプリング取着装置の改良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a return spring attachment device for a small engine starting lever of a motorcycle or the like.

オートバイ等の小型エンジンは、キックレバー等で始動
軸を回し、エンジンのクランク軸を回転させて、エンジ
ンを始動する。A small engine such as a motorcycle is started by turning a starting shaft using a kick lever or the like to rotate the engine crankshaft.

そして、始動軸には、戻りスプリングを装着し、キック
レバーを離すと、元の位置に戻るようになっている。A return spring is attached to the starting shaft so that it returns to its original position when the kick lever is released.

この、戻りスプリングは、ケースカバーの内側に装着さ
れ、ケースカバーの内側は、凹部になっているので、組
立てのとき、手を入れて作業するのに不都合で、戻りス
プリングが取着し難くて手数がかかる。This return spring is attached to the inside of the case cover, and since the inside of the case cover is recessed, it is inconvenient to put your hands in during assembly, and it is difficult to install the return spring. It takes time.

又、戻りスプリングには、ガイド片を設ける等、コスト
高にもなっている。In addition, the return spring requires a guide piece, which increases the cost.

この考案は、かかる点に鑑み改善したもので、以下図面
に示す本考案の実施例について説明する。This invention has been improved in view of these points, and an embodiment of the invention shown in the drawings will be described below.

エンジンのケース１に軸孔２を設けて、始動軸３を軸架
する。A shaft hole 2 is provided in a case 1 of an engine, and a starting shaft 3 is mounted thereon.

軸孔２の外側には凹部４を設け、この凹部４内に、コイ
ル状の戻りスプリング５を挿入する。A recess 4 is provided outside the shaft hole 2, and a coiled return spring 5 is inserted into the recess 4.

そして、戻りスプリング５の一端を、始動軸３の孔６に
掛止し、他端を、凹部４の一側に設けた切欠き７に掛止
する。One end of the return spring 5 is hooked to the hole 6 of the starting shaft 3, and the other end is hooked to the notch 7 provided on one side of the recess 4.

更に、始動軸３に、軸筒８に割溝９を設けたカバーガイ
ド１ｏを挿入し、始動軸３の外端には始動レバー１１を
締着する。Further, a cover guide 1o having a groove 9 provided in the shaft cylinder 8 is inserted into the starting shaft 3, and a starting lever 11 is fastened to the outer end of the starting shaft 3.

１２はオイルシールである。作用について説明する。12 is an oil seal. The effect will be explained.

戻りスプリング５は、ケース１に始動軸３を軸架してか
ら、外側から装着できる。The return spring 5 can be mounted from the outside after the starting shaft 3 is mounted on the case 1.

そして、戻りスプリング５は、始動軸３と切欠き７に掛
止されて、始動軸３を始動レバー１１で回動した後、始
動レバー１１を離すと、弾力によって、始動軸３が元の
位置に復する。The return spring 5 is hooked onto the starting shaft 3 and the notch 7, and when the starting shaft 3 is rotated by the starting lever 11 and then the starting lever 11 is released, the starting shaft 3 returns to its original position due to its elasticity. Return to

カバーガイド１０は、戻りスプリング５が見えないよう
に覆うと共に、軸筒８の外周が、戻りスプリング５のガ
イドになる。The cover guide 10 covers the return spring 5 so that it cannot be seen, and the outer periphery of the shaft cylinder 8 serves as a guide for the return spring 5.

そして、カバーガイド１０は、割溝９が設けであるので
、戻りスプリング５を装置してから楽に取着できる。Since the cover guide 10 is provided with the groove 9, it can be easily attached after the return spring 5 is installed.

以上説明したように、この考案は、ケースの軸孔に軸架
した始動軸を設け、軸孔外端に凹部を設け、該凹部に挿
入したコイル状の戻りスプリングの両端を始動軸の孔と
、凹部−側の切欠きに各々掛止し、軸筒に割溝を設けた
カバーガイドを始動軸に挿入し、始動軸端に始動レバー
を取着するようにしたので、戻りスプリングがケースの
外側から容易に取着できる。As explained above, this invention provides a starting shaft that is suspended in the shaft hole of the case, a recess is provided at the outer end of the shaft hole, and both ends of the coiled return spring inserted into the recess are connected to the hole of the starting shaft. , a cover guide with a slot on the side of the recess is inserted into the starting shaft, and the starting lever is attached to the end of the starting shaft, so that the return spring does not close to the case. Can be easily attached from the outside.

そして、カバーガイドは、戻りスプリングを覆って見え
ないようにすると共に、戻りスプリングのガイドを兼ね
ることができる。The cover guide covers the return spring so that it cannot be seen, and can also serve as a guide for the return spring.

又、始動軸端に始動レバーを締着することによって、戻
りスプリングとカバーガイドの外れ止めができ、特別に
締着用の部品を必要とせず、安価にできる。Furthermore, by tightening the starting lever to the end of the starting shaft, the return spring and cover guide can be prevented from coming off, and no special tightening parts are required, making it possible to reduce the cost.
