The rotary shaft 134 is rotated, and the rotary shaft 134 rotates the hollow shaft 81 to change the speed of the hydraulic continuously variable transmission 83.

When the motor 155 operates, the gear 1
54, gear 153, gear 152, gear 151, gear 15
0, the rotation is transmitted to the gear 149, the rotation of the gear 149 is transmitted to the plate 146 via the sliding member 148, and the plate 146 rotates the throttle lever 143 via the rod 145 to move the wire 144 up and down. Activate.

The cross link mechanism 1 of the second embodiment
6, the direction of the upper plate 19 and the lower plate 26 is set to the left and right direction, and the direction of the inner cross link rod 21 and the outer cross link rod 24 of the cross link mechanism 16 is also set to the left and right direction. Since the load is evenly distributed to the front upper horizontal shaft 20 and the upper sliding shaft 23, play is prevented.
