【発明の詳細な説明】 産業上の利用分野 この発明は、トラクタ等の走行ペタルに関する。[Detailed description of the invention] Industrial applications The present invention relates to a running pedal for a tractor or the like.
従来の技術、および発明が解決しようとする課題
ペタルの踏込操作によって、前進増速と後進増速とに切

進ペタルと後進ペタルとの操作位置、乃至形態によって
、操作性を異にする。これらのベタルを左右位置に並べ
た形態とするときは。BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a tractor that operates by switching between forward speed increase and reverse speed increase by depressing a pedal, it is difficult to determine the operational position of the forward and reverse pedals. Operability varies depending on the form. When these Betals are arranged in left and right positions.
左右に踏換えて操作するために安全性は高く、比較的錯
誤りを少くすることができるが、前後進を小間隔で繰返
す場合は、面倒である。Since the operation is performed by switching from side to side, safety is high and errors can be relatively reduced, but it is troublesome when the movement is repeated at small intervals.
課題を解決するための手段
この発明は、中立位置から前側への踏込によって前進増

タルの構成とする。Means for Solving the Problems This invention provides a forward pedal (1) that accelerates forward by stepping forward from a neutral position, and a reverse pedal (2) that increases backward speed by pressing rearward from a neutral position. The driving pedal of a tractor or the like is provided so as to be switchable between the position and the left and right depression positions.
発明の作用、および効果
前進ペタル（１）と後進ペタル（２）とを前後の位置に
切換えた状態では、これらの上側に操作側の足を載せて
、爪先側で前進ペタル（１）を踏込むと、この前進ペタ
ル（１１の回動量に応じて中立位置から前進増速される
。又、この踏込を戻すと前進ペタル（１）は中立位置側
へ戻り、減速される。踵側で後進ベタル（２）を踏込む
と、この後進ペタル（２）の回動量に応じて中立位置か
ら後進増速される。Functions and Effects of the Invention When the forward pedal (1) and the reverse pedal (2) are switched between the forward and backward positions, place the operating foot on top of them and step on the forward pedal (1) with the tip of the foot. When the pedal is depressed, the forward speed is increased from the neutral position according to the amount of rotation of the forward pedal (11).When the pedal is released, the forward pedal (1) returns to the neutral position and is decelerated.The heel side moves backward. When the pedal (2) is depressed, the reverse speed is increased from the neutral position in accordance with the amount of rotation of the reverse pedal (2).
又、前進ペタル（１）と後進ペタル（２）とを左右の踏

２１間を踏換えることによって行う。Furthermore, when the forward pedal (1) and the reverse pedal (2) are switched to the left and right depression positions, both these pedals (11 (2) can be depressed with the toe side to increase the forward speed or reverse speed. At this time, the tip of the toe should touch both of these petals (1) (
This is done by changing the interval between 21 and 21.

機動性を重視するときは前後位置に切換えるなど、作業
状態に応じた操作形態とすることができる。By switching the forward pedal (1) and the reverse pedal (2) between the front and rear depression positions and the left and right depression positions in this way, for example, when safety is important, the pedals can be switched to the left and right positions,
When mobility is important, the operation mode can be changed to suit the working condition, such as switching between front and rear positions.

Shift control shaft (4) and control arm integrated therewith [5]
Rotate from the neutral position (N) to the forward position (F) or reverse position (R), and enter the neutral position! The forward travel speed is increased according to the amount of rotation from the transmission stop state (N) to the forward position (F), and the forward travel is decelerated by returning to the neutral position (N). The same holds true for rotation to the reverse position (R), at which time the transmission rotation direction is reversed. or,
This speed change control shaft (4) is always resiliently biased to return to the neutral position (N).
