The arm 35 is rotatably and pivotally attached to the position 4. A U-shaped bracket 36 is fixed to one end of the arm 35 to pivotally mount the rotation base portion 25a of the change lever.
The rod 37 for switching the auxiliary shift is connected to the other end of the
The tip portion is fastened to the L-shaped piece 38. Then, the other end of the L-shaped piece 38 is pivotally attached to the rotating arm 40 of the auxiliary shift switching shaft 39. On the other hand, the rotation base 25a of the change lever
An L-shaped bent arm 41 is fixedly attached to the end of the arm 41, and a rod 42 for switching the drive system is attached to the tip of the arm 41.
To connect. Then, the other end of the rod 42 is pivotally attached to the rotating arm 44 of the drive system switching shaft 43.

いる。Thus, the change lever 25 has the guide groove 2
9 is in the neutral position, the axis L 1 of the boss 34 and the ball joint 45 of the rod 42 pivotally attached to the arm 41.
And the axis L 2 of the same coincide with each other on the same axis. Further, as shown in the figure, when the change lever 25 is located in the long groove of the guide groove 29, the drive system is in the two-wheel drive mode.

る。When the change lever 25 is moved in the long groove of the guide groove 29 in the direction of the arrow X 1 , the rotation lever base 25a of the change lever presses the bracket 36, and the arm 35 moves about the boss 34 as a center. Rotate clockwise in the figure. Then, the rod 37 for switching the sub-transmission, which is connected to the other end of the arm 35, is pushed down, the pivot arm 40 pivots in the direction of the arrow L, and the sub-transmission device switches to the low speed side. Therefore, the traveling mode becomes the two-wheel drive low speed mode.

When rotating in the direction, first, as described above, the arm 3
5 rotates around the boss 34 in the clockwise direction in the figure, the rod 37 is pushed down, and the sub transmission is switched to the low speed side. Further, the arm 41 pivots downward around the bracket 36 as a fulcrum, the ball joint 45 deviates from the axis L 2 and the rod 42 is pushed down, the pivot arm 44 pivots in the direction of the arrow W, and the drive system is changed to four. Switch to wheel drive mode. Therefore, the traveling mode becomes the four-wheel drive low speed mode.
