勝ちであり、又、フロアの下方等の狭い個所に、
これらの操作ペダルを組付ける作業は、極めて不
便であつた。 The brake pedal and clutch pedal, which are installed near the bottom of the meter panel and near the top of the floor, must be supported with sufficient shaft support rigidity to withstand the operating force that is applied to them when the pedal is depressed. However, it is necessary to install the shaft support bracket in such a way that it does not interfere with getting on and off the tractor, so conventionally a small bearing bracket was installed on the floor or transmission case for each operation pedal. It is common and tends to lack shaft support rigidity, and is suitable for use in narrow places such as under the floor.
The work of assembling these operating pedals was extremely inconvenient.

ダルを取付けたものである。 Also, conventionally known devices of this kind include those described in Japanese Patent Application Laid-Open No. 49-92722 and those described in Japanese Utility Model Application Publication No. 57-137567. The former is designed to adjust the driver's driving position by sliding the mounting member in the front and back direction relative to the body.
In the latter case, a support shaft of an operating tool is attached between the left and right vertical walls of the mounting member, and a brake pedal and a clutch pedal are attached to the support shaft.

容易ではない。 Therefore, in the former, the rigidity of the mounting shaft for the brake pedal, etc. is poor and it is inconvenient to assemble, while the latter has a gate-shaped mounting member, but the brake pedal or clutch pedal is Since it is provided inside the gate-shaped mounting member, it is not easy to operate by stepping on it.

のである。 SUMMARY OF THE INVENTION Therefore, the present invention aims to eliminate the above-mentioned defects, and has the brake pedals 8 and 9 and the clutch pedal 1 installed in the upper part of the clutch housing 1.
In the operation member supporting device, which is provided with a casing 2 that supports each rotation base of 1 and has a pair of vertical walls 2a, 2a on the left and right, the casing 2 for supporting the pedal is It has vertical walls 2a, 2a, and the vertical walls 2a, 2a
Brake pedals 8, 9 and a clutch housing 11 are arranged on the outside of the vertical walls 2a, 2a.
Horizontal shafts 5 and 7 are provided on both the clutch housing side and the horizontal shafts 5 and 7 are supported in the vertical direction by connecting rods, and the vertical wall 2
A tractor characterized in that a tilt fulcrum shaft 38 of a shaft mast 36 of a handle shaft 35 is provided in a part of a, and a mechanism for locking the tilt mechanism is provided between the left and right vertical walls 2a, 2a. An object of the present invention is to provide a support device for an operating member in.

破壊を防止できるのである。 Thus, in the present invention, since the pedals are disposed outside the vertical walls 2a, they do not get in the way during operation, and the connecting rods are also located outside, making it easy to adjust the link length. . In addition, since the pedals can be sub-assembled in advance, the assembly work is facilitated.Furthermore, since the upper portions of the left and right vertical walls are connected by the horizontal shaft, the rigidity is increased and the pedals can be firmly supported. Since a tilt lock mechanism is provided between the vertical walls, there is no need for special covers, and damage and destruction to these can be prevented.
