Description
ブレーキペダルと速度保持機構のロック解除用操作部材とを、車体下方を横切って配備された操作ワイヤで連動連結するとともに、車体の後方下部から車体の左右中央部下部に沿って前方に向けて延出配備された前輪駆動用の伝動軸と車体との間の空隙に前記操作ワイヤを挿通し、前記操作ワイヤを下方から支持するワイヤ受け部材を、側面視で前記伝動軸の下端と車体との間に位置するように配設してあることを特徴とする。
また、ワイヤ受け部材で下方から受け止め支持された操作ワイヤは垂れ下がることがないので、たるみを持たせた余裕のある長さの操作ワイヤを配備することができる。
また、操作ワイヤを無理に曲げなくてもアウタワイヤ端部を所定の方向に向けてワイヤ受け部材などに固定支持することが容易となる。
前記ワイヤ受け部材を、車体側に固定された左右に長い丸棒材と、この丸棒材から後方に延出された受け板とを備えて構成してあるものである。
前記操作ワイヤを平面視でS字状に屈曲配備し、前記丸棒材の左右両端部を、S字状に屈曲配備した前記操作ワイヤの左右両端部近くにまで延出し、前記受け板を、左右に離間して配設された左右の受け板で構成して、S字状に屈曲配備した前記操作ワイヤの2つの屈曲頂部付近を、この左右の受け板でそれぞれ下方から支持するように構成してあるものである。

- 無段変速装置を任意の変速位置に保持する速度ロック機構を車体の横一側に備え、機体の横他側に配備されたブレーキペダルによる走行停止操作に連動して前記速度ロック機構のロック解除用操作部材を強制解除操作するよう構成したトラクタの変速操作構造において、
ブレーキペダルと速度保持機構のロック解除用操作部材とを、車体下方を横切って配備された操作ワイヤで連動連結するとともに、
車体の後方下部から車体の左右中央部下部に沿って前方に向けて延出配備された前輪駆動用の伝動軸と車体との間の空隙に前記操作ワイヤを挿通し、
前記操作ワイヤを下方から支持するワイヤ受け部材を、側面視で前記伝動軸の下端と車体との間に位置するように配設してあることを特徴とするトラクタの変速操作構造。 - 前記ワイヤ受け部材を、車体側に固定された左右に長い丸棒材と、この丸棒材から後方に延出された受け板とを備えて構成してある請求項1記載のトラクタの変速操作構造。
- 前記操作ワイヤを平面視でS字状に屈曲配備し、
前記丸棒材の左右両端部を、S字状に屈曲配備した前記操作ワイヤの左右両端部近くにまで延出し、
前記受け板を、左右に離間して配設された左右の受け板で構成して、S字状に屈曲配備した前記操作ワイヤの2つの屈曲頂部付近を、この左右の受け板でそれぞれ下方から支持するように構成してある請求項2記載のトラクタの変速操作構造。
