【発明の詳細な説明】 〔産業上の利用分野〕 本発明は歩行型耕耘機の変速用操作レバー取付構造に
関する。Description: TECHNICAL FIELD The present invention relates to a gear shift operation lever mounting structure for a walk-type cultivator.
歩行型耕耘機では、歩行系、PTO系等の変速を行う変
速用操作レバーをトランスミッションケースの近傍に配
設させる手法を用いることが多い。In a walk-type cultivator, a method of arranging a shift operation lever for performing a shift, such as a walking system or a PTO system, in the vicinity of a transmission case is often used.
このような例として、実開昭63−110126号公報で示さ
れるように、ミッションケース側のボスに変速操作レバ
ーを嵌入連結してあるとともに、このレバーの根元を囲
繞するカバーをその内側の取付部でミッションケースへ
ボルト締着したものが知られている。As an example of this, as shown in Japanese Utility Model Laid-Open No. 63-110126, a gear shift operation lever is fitted and connected to a boss on the mission case side, and a cover surrounding the base of the lever is attached inside the boss. It is known that some parts are bolted to the mission case.
前記従来技術では、変速操作レバーはミッションケー
ス側の揺動軸まわりで授動するボスへ取り付けるもので
あり、かつ、カバーもミッションケースに取り付けられ
ているので、製品誤差、組付誤差の相乗効果が大きくな
りレバーとこのレバー挿通用のカバーの孔との相対位置
ズレが大きくなるものであった。従って、孔の大きさが
大きくなり、レバーとの間隙も大となり、カバーの内側
が見え易くなって外観が劣る原因になっていた。In the above-mentioned prior art, since the gear shift operation lever is attached to the boss that is driven around the swing shaft on the mission case side, and the cover is also attached to the mission case, there is a synergistic effect of product error and assembly error. Therefore, the relative position deviation between the lever and the hole of the cover for inserting the lever becomes large. Therefore, the size of the hole becomes large, the gap between the hole and the lever becomes large, and the inside of the cover is easily visible, which causes the appearance to be poor.
また、カバーをミッションケースへ取付けるための取
付部がカバーの内側で、かつ、奥まった部位に設けてあ
るのでその着脱操作が行い難い不都合があった。Further, since the attachment portion for attaching the cover to the mission case is provided inside the cover and in a recessed portion, it is difficult to perform the attachment / detachment operation.
本発明は上記不都合を解消せんとする点に目的を有す
る。The present invention has an object to solve the above inconvenience.
上記目的を達成するために本発明は、トランスミッシ
ョンケースの近傍に、このトランスミッションの変速用
操作レバーをケース側に一体に固定されている片持梁状
支持体へ揺動自在に枢支させるとともに、固定された支
持体の先端に前記操作レバーの根元部を覆うカバーの取
付部を設けてあることを特徴とする。In order to achieve the above object, the present invention, in the vicinity of a transmission case, pivotally supports a transmission operation lever of this transmission to a cantilever support integrally fixed to the case side, It is characterized in that a mounting portion of a cover for covering the base portion of the operation lever is provided at the tip of the fixed support body.
つまり、操作レバーを枢支した固定物である支持体に
対してカバーを直接取付けてあるから、カバーとレバー
の間に介在する部品数が従来より少なくなり、その分両
者の間に発生する製品誤差、組付誤差が少なくなる。In other words, since the cover is directly attached to the support, which is a fixed object that pivotally supports the operation lever, the number of parts interposed between the cover and the lever is smaller than in the past, and the product generated between them is correspondingly reduced. Errors and assembly errors are reduced.
また、カバーの取付部を支持体の先端に設けることに
より、この取付部の位置を従来に比べて反ミッションケ
ース側、すなわち耕耘機の外側方へ寄せて配置させるこ
とができる。Further, by providing the attachment portion of the cover at the tip of the support, the position of the attachment portion can be arranged closer to the side opposite to the mission case, that is, the outer side of the cultivator, as compared with the conventional case.
従って、レバーとカバーのレバー挿通用孔との相対位
置ズレが小となるので予め設定する間隙も少なくできる
ことにより、カバー内が見えにくくなって外観を悪化さ
せる原因となり難いようにすることができた。Therefore, since the relative position deviation between the lever and the lever insertion hole of the cover is small, it is possible to reduce the preset gap, thereby making it difficult to see the inside of the cover and causing the appearance to deteriorate. .
そして、カバーの取付部に手指が届きやすく、またそ
の位置の確認もしやすくなって、このカバーの着脱操作
を行い易いものにすることもできた。Then, the fingers can easily reach the mounting portion of the cover, and the position thereof can be easily confirmed, so that the cover can be easily attached and detached.
しかも、その手段が、ミッションケースに付設の支持
体にレバーの枢支点とカバーの取付部との両方を設ける
だけの簡単な構造であるから、別々に設けた場合に比べ
て支持体を有効利用して経済的にも好ましいものにし得
た。Moreover, since the means is a simple structure in which both the pivotal fulcrum of the lever and the mounting portion of the cover are provided on the support body attached to the mission case, the support body is effectively used compared to the case where they are provided separately. And economically favorable.
以下に、本発明の実施例を図面に基づいて説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
