In the state shown in FIGS. 1, 2, 4 and 9 in which the telescopic rod 39 is shortened, the left and right front wheel vicinity portions 11 are close to the center of the vehicle body width, and the steering front wheel 2 is limited in steering angle. However, the outer surface of the front wheel vicinity portion 11 and the outer surface of the fairing 4 are flush with each other, the running air resistance during high speed running is reduced, and the fuel efficiency is good.
[0029]
1, 2, 4 and 9, when the electric cylinder 38 is driven in one direction to extend the telescopic rod 39, the bracket 41 is moved forward as shown in FIG. The bell flank 42 swings clockwise about the shaft 43, and the connecting pin 48 moves outward (to the right) and moves slightly forward, and is connected to this and connected to the connecting pin 48 49 also slightly swings counterclockwise about the one end 47a of the arm 47, and the front wheel vicinity portion 11 opens largely outward with the rear portion 11b as the center, so that the steering front wheel 2 takes a large steering angle. And can make a sharp turn with a small turning radius.
[0030]
Thus, in a high-speed traveling state, the mutual distance between the left and right front wheel vicinity portions 11 located in front of the left and right front end face portions 4a of the fairing 4 is reduced, and the gap between the fender 10 and the front wheel vicinity portion 11 is reduced. The motorcycle 1 can be made into a refined body shape by forming the front part of the fairing 4 including the front wheel vicinity part 11 into an elongated shape, and at a low speed. At the time of steering or handling, the motorcycle 1 can be run or moved with a small turning radius by turning the steering front wheel 2 greatly.
