る。[Detailed Description of the Invention] [Industrial Application Field] The present invention is designed to prevent a member for engaging with a transmission arm from being removed from the protruding end of a push-pull type shift fork shaft that protrudes outward from a transmission case. At the same time, the gauge portions protruding from the engagement member are engaged with the guide grooves of a speed change guide plate fixed to the transmission case, and each of the gauge portions is formed on the surface of the speed change guide plate. The present invention relates to a speed change operation structure for a walking agricultural machine that is provided with a speed change display corresponding to the speed change position.
〔従来の技術〕
この種の変速操作構造において、従来は、前記
案内溝の上方を開放して各変速駆動位置を何れの
位置においても、ゲージ部が目視できるように構
成してあつた（例えば実願昭59−33312号）。[Prior Art] Conventionally, in this type of shift operation structure, the upper part of the guide groove is opened so that the gauge part can be visually observed at any shift drive position (for example, Jitsugan No. 59-33312).
しかし、二つのゲージ部が同時に見える為に操
作すべき対象のゲージ部に対する瞬間的な判断が
できにくく、操作に手間取ることがあつた。
However, since two gauge parts are visible at the same time, it is difficult to make an instantaneous determination of the target gauge part to be operated, and the operation sometimes takes time.
本考案の目的は変速操作を良好にできるものを
提供する点にある。 An object of the present invention is to provide a device that can improve gear shifting operations.
本考案による特徴構成は前記案内溝の中立位置
に、前記ゲージ部を覆い隠す部材を設けてある点
にあり、その作用効果は次の通りである。
A feature of the present invention is that a member is provided at a neutral position of the guide groove to cover the gauge portion, and its effects are as follows.
つまり、変速対象となるゲージ部が二つのうち
の必ず一方のものだけであり、しかも、他の一方
はその時には中立位置にある点に着目して、前記
案内溝の中立位置対応部分に覆い部材を設けるだ
けで、両ゲージ部が中立位置にある状態から変速
操作するにしても、何れのゲージ部が操作された
が一目瞭然であり、変速位置にあるゲージ部を中
立位置に戻すにしても、変速位置にあるのは一つ
だけしか見えないので、その分操作に手間取るこ
とはない。
In other words, focusing on the fact that only one of the two gauge parts is subject to gear shifting, and the other one is at the neutral position at that time, a covering member is attached to the part of the guide groove corresponding to the neutral position. By simply providing a , it is obvious which gauge part was operated even if the gear is changed from a state where both gauge parts are in the neutral position, and even if the gauge part in the gear shift position is returned to the neutral position, Since only one gear is visible at the shifting position, it does not take much time to operate it.
