本考案は、農用トラクタのレバー取付け構造に
関し、詳しくは、運転座席の側方に設けた各種操
作レバーを支軸周りに揺動可能に構成してあるも
のに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a lever mounting structure for an agricultural tractor. Specifically, the present invention relates to a lever mounting structure for an agricultural tractor. Concerning what is being done.
従来、上記レバー取付け構造としては、例えば

Conventionally, as the above lever mounting structure, as shown in Japanese Utility Model Application Publication No. 54-116329, for example, a support that supports the operating lever is attached to the side of a plate-shaped frame that supports the driver's seat via a frame that is a separate member. Some have a fixed configuration with the shaft facing outward.
一般に、運転座席を支持するフレームは、強度

段も改善の余地があつた。
Generally, it is desirable that the frame that supports the driver's seat has high strength. However, if a reinforcing member is provided as a separate member in order to improve the strength of the frame, the structure becomes complicated and the manufacturing process becomes labor-intensive. Furthermore, increasing the thickness of the frame to improve its strength increases the weight, and both methods leave room for improvement.
本考案の目的は、前記支軸を合理的に利用し
て、運転座席の支持強度を向上させる点にある。 An object of the present invention is to rationally utilize the support shaft to improve the support strength of the driver's seat.

び効果は次の通りである。
The feature of the present invention is that a pair of left and right frames for mounting the driver's seat is provided on the upper part of the transmission case, and the left and right frames are connected and fixed with a left and right support shaft passing through each of the left and right frames. Various operating levers are loosely fitted and supported on the protruding portions of the support shaft that protrude from the body in the left and right outward directions, respectively, and their functions and effects are as follows.
つまり、上記の如く、支軸を左右枠体の夫々に
亘つて貫通した状態で連結固定してあるので、左
右の枠体に比較的薄い部材を用いても、左右の枠
体と支軸とで剛体構造になるので枠体の左右方向
への変形を防ぐことができる。
In other words, as mentioned above, since the support shaft is connected and fixed in a state that passes through each of the left and right frames, even if relatively thin members are used for the left and right frames, the left and right frames and the support shaft can be connected. Since it has a rigid structure, it is possible to prevent the frame from deforming in the left-right direction.
又、支軸の端部に操作レバー類を遊嵌支持させ
ているので、複数の操作レバー類を、夫々共通の
揺動軸心で揺動させることができる。 Further, since the operating levers are loosely fitted and supported at the ends of the support shafts, the plurality of operating levers can each be swung about a common oscillating axis.
従つて、支軸を合理的に利用するだけで、ステ
ー等を用いず、又、重量の増大を招くことなく、
運転座席の支持強度が向上した。
Therefore, by rationally using the support shaft, without using stays, etc., and without causing an increase in weight,
The support strength of the driver's seat has been improved.
しかも、複数の操作レバーを共通の揺動軸心で
操作できるので、多数の操作レバー類を同じ操作
感覚で操作できる効果も奏する。 Moreover, since a plurality of operating levers can be operated with a common pivot axis, it is possible to operate a large number of operating levers with the same operating feeling.
