式にも本発明を適用できることは勿論である。The horizontal screw shaft 7 and the horizontal shaft (third shaft) 20 of the transmission case are transmitted through the pawl clutch 9, and at the upper and lower limits of the connecting link 2, the pawl inclined surface 9a of the pawl clutch 9 is used. The claw slides and escapes, so that the rotational drive of the horizontal screw shaft 7 is stopped. The pawl clutch 9 can be operated by operating a clutch operating mechanism (not shown) regardless of work (rotation of a traveling output shaft and a work drive shaft) of the horizontal screw shaft 7 in the forward and reverse directions.
By controlling the stop, the vertical position of the wheel can be changed. When adjusting the vertical position of the wheels, the horizontal screw shaft is rotatably driven by the power from the mission case, and the pivotal point of the connecting link (the pivot 2C ) Is changed back and forth to change the inclination angles of the links A and B to extend and contract the connecting link 2 in the vertical direction, the effective length of the connecting link 2 is changed from La to Lb, and the vertical position of the wheel is adjusted. (See FIG. 3). At this time, the operation of the pawl clutch 9 automatically stops the front-rear moving shaft at the upper limit position or the lower limit position of the wheel, and the adjustment of the vertical position of the wheel is prevented. In the embodiment, the two-wheel type in which the traveling vehicles are arranged on both sides of the wheel case 10 is used, but it goes without saying that the present invention can be applied to the one-wheel type.

作業を行いつつ上下位置調節操作を行うことができる。As described above, according to the present invention, the rotation of the horizontal screw shaft is interlocked with the vertical expansion and contraction of the connecting link through the horizontal movement of the horizontal L metal fitting and the front-rear moving shaft, so that the horizontal screw driven by the power is transmitted from the transmission case. Since the shaft is rotated to expand and contract the connecting link in the vertical direction to change the vertical position of the wheel, it is possible to easily adjust the vertical position of the wheel as a power system for women and women. On the other hand, by moving the pivot point (coaxial axis 2C) of the connecting link back and forth,
The load for the vertical position adjusting operation of the wheels is small, and the vertical position adjusting operation can be performed while performing various operations.
