As a result, the trunnion shaft 14a is operated to rotate forward. When the main shift lever 27 is tilted rearward, an upward pulling force is transmitted to the main shift rod 82, and the swing arm 83 swings upward. As a result, the trunnion shaft 14a is operated to rotate backward.

  Here, in FIG. 3, for example, when the upper end of the main transmission rod 82 is connected to the base 27a of the main transmission lever 27 in a state where it is located on the rear side with respect to the axis X1 in a side view, When the main transmission rod 82 extends from the base 27a of the main transmission lever 27 toward the trunnion shaft 14a in order to connect the lower end of the main transmission rod 82 to the swing arm 83, the main transmission rod 82 is moved to the upper part (HST) of the transmission T. The lower part of the main transmission rod 82 needs to be greatly bent so as not to interfere with the filter 14b).

  However, in the present embodiment, as described above, the upper end of the main speed change rod 82 is connected to the base 27a of the main speed change lever 27 in a state where it is located on the front side with respect to the axis X1 in a side view. The lower end of the main transmission rod 82 can be connected to the tip of the swing arm 83 without significantly bending the lower part of the transmission rod 82. Thereby, the strength of the main transmission rod 82 can be improved.
