作が容易化されると云う効果を得たのである。That is, a cabin (4) is pivotally supported to the heavy frame (1) so as to be able to swing from side to side, and is provided with a hydraulic cylinder so that it can be tilted left and right, and an attitude detector (4) is installed to detect the left and right attitude of the cabin (4). 14) Based on the operation of the cabin (4)
Interlocking control is performed to maintain the left and right sides in an approximately horizontal position. As a result, the cabin 14) is always maintained in a substantially horizontal position regardless of the horizontal inclination of the tractor, which reduces fatigue during operation and facilitates equipment operation. be.

The front bearing body (3) is attached near the right center, and the center pin (5) is fixed near the left and right center in the front part of the cabin (4), as shown in the side view in the figure and the rear view in Fig. 2. is fitted into the front bearing body (3) so that it can only rotate freely, and then the body frame (1)
A rear bearing body (6) is attached to the upper left and right center of the cabin (4), which forms the rear part of the cabin (4). Cabin (4) is fitted so that it can be rotated freely.
is pivotally supported to the vehicle body frame (1) so that it can be swung from side to side. And the lower frame (8) of the cabin (4)
on either the left or right side of the vehicle body frame (1
) as Noriya transmission case, hydraulic cylinder (9
) and its piston (10), and the pressure oil from the oil pump (12) installed on the tractor to raise and lower the work equipment lifting mechanism 0υ is transferred to the hydraulic cylinder ( 9) and connect it to supply the cabin (
An attitude detector (14) for detecting the left-right tilt of the cabin (4) is installed near the center in the left-right direction of the cabin (4), and the switching valve (13) is operated based on the detection operation of this attitude detector (14). The piston 00) is controlled to move in and out, thereby maintaining the cabin (1) substantially horizontally from side to side.

7L x 18L) are connected to the switching valve (11a of 1 millimeter) required solenoid (13RX13L), respectively.
The short-circuited pole piece at Minamata (15), which moves to the higher side with the slope of f7 (l[i), is energized, and the pressure oil of the oil pump (12) is supplied to the cylinder (9) K. At the same time, the remaining oil in the cylinder (9) is discharged into the tank (19) to maintain the horizontal posture of the cabin r4.
