At step 3, the stay sides of each of the link members 28 and 29 are tightened.

A pair of left and right blinkers 34 and 35 are attached to the outer surface of the intermediate portion of each headlight stay 22, 24.

On the other hand, the shape of the headlight cup <-37 of the headlight 36 supported between the headlight stays 22 and 24 is approximately rectangular in front, and the rear width in the plane is small, that is, the width is relatively small at the center of the rear as shown in the figure. It is formed by a convex portion 37a that bulges out to the rear. The reason for this shape is that the socket 40 of the pulp 39 attached to the center of the light unit 38 provided inside the headlight 36 as shown by the broken line in FIG. 37 can also be formed by following the outer shape of the light unit 38.

In addition, horizontal platens 41 and 42 are provided on both rear sides of the headlight 36. That is, since the rear portion of the headlight cover 37 is formed with a convex portion 37a having a smaller width,
Horizontal brackets 41 and 42 are integrally formed on both sides of the frame. Each of these brackets is for headlight cover 3
It is desirable that it does not protrude beyond the left and right width and front and back width of 7.

In addition, the brackets 41 and 42 are a pair of upper and lower platens (41a) separated by a predetermined width vertically, respectively, as shown in FIG.
, 41b, and 42a, 42b.

Therefore, each inner end (headlight side) of the link member 28, 29 forms an overall planar shape that follows the shape of the rear part of the headlight 36, and has a pair of upper and lower mounting edges 28a, 28b, and 29a, respectively. , 29-b are bent to have a U-shaped cross section, and are held between the brackets 41 and 42, respectively. Therefore, the inner ends of the link members 28 and 29 are designed to fit on both sides of the convex portion 37a having a small rear width of the headlight.

As shown in FIG. 5, with the mounting edges 28a and 28b of the left link member 28 clamped to the bracket 41, holes are formed vertically through both of them, and the upper and lower brackets 41a , 41b, and the link member 28 and the bracket 41 are fastened freely in a twilled manner using fixing means such as bolts 44 and nuts 45.

On the other hand, the edge 29a of the link member 29 on the right side.

With the bracket 29b being clamped to the bracket 42, holes are formed vertically through the bracket 42, and elongated holes 46 are formed in the bracket 42 in the approximately front-rear direction as shown in FIG. A collar 47 is interposed between the upper and lower brackets 42a and 42b, and the twill wire is freely fastened using fixing means such as bolts 48 and nuts 49. In addition, link member 2
