8a so that the fuel tank 1 can be accurately positioned.
8 is attached.

The cowling panel 35 and the like are attached to the vehicle body frame 11 so as to be adjustable in position. That is, the head pipe 19 of the body frame 11
As shown in FIG. 5, a substantially triangular stay 55 is fixed to the front side when viewed from the side.
As shown in FIG. 3, a projecting pin 5 projecting horizontally in the vehicle width direction.
6 is fixed, and the protruding pin 56 is fitted to an elastically deformable rubber-made substantially cylindrical damper member 57 as a “fitting portion”.

A fitting recess 35h into which the damper member 57 is fitted is formed inside the front half of the cowling panel 35. The fitting recess 35h has a pair of upper and lower horizontal walls having a substantially horizontal surface. 35i and a vertical wall formed so as to connect the front end of each horizontal wall 35i, the rear side of the vehicle is configured to be open. Furthermore, each horizontal wall 3
Rib 35j having a vertical surface for supporting 5i
Are formed integrally with the cowling panel 35 and the horizontal wall 35i.

By moving the cowling panel 35 from the front to the rear of the vehicle, the damper member 57 is fitted into the fitting recess 35h. In this fitted state, the rear edge 35g side of the cowling panel 35 is movable in the front-rear and left-right directions of the vehicle, and the cowling panel 35 is rotated around the circular damper member 57, thereby causing the cowling panel 35 to rotate.
The rear end edge 35g side is configured to be movable in the vertical direction and to be position adjustable.

Also, when the damper member 57 is sandwiched between the pair of horizontal walls 35i, the load can be received at the front portion of the cowling assembly including the headlights 36 and the like, and when the vehicle behaves such as pitching. The assembly is securely supported to prevent rattling.

Further, as shown in FIG. 14, a bracket 60 is fixed to the down tube 22, and a fixing pin 61 protruding toward the front of the vehicle is fixed to the bracket 60. The fixing pin 61 is attached to the body front under 50. It is inserted into the fitting hole 62a of the attached rubber ring-shaped damper member 62. A mounting piece 50a is formed in the body front under 50 as shown in FIG.
The damper member 62 is formed in the long hole 50b.
Are fitted. Although not shown, the fitting hole 62a formed in the damper member 62 is a vertically long hole like the long hole 50b of the mounting piece 50a.

Thus, in this portion, the body front under 5 fixed to the cowling panel 35 is provided.
Reference numeral 0 is provided so as to be movable in the vehicle front-rear direction and the up-down direction with respect to the down tube 22 of the vehicle body frame 11 via the fixing pin 61 and its long hole, so that the position can be adjusted.

Next, the order of mounting the cowling panel 35 and the like will be described.

First, the headlight 36, the front window panel 39, the front flasher lamp 43, and the body front under 50 are mounted on the cowling panel 35. Thereby, naturally, the cowling panel 35 can be used.
The headlight 36 and the like can be attached without any gap or the like in the mating portion.

Thereafter, the sub-assembled cowling panel 35 is moved rearward from the vehicle front side, so that the damper member 57 is inserted into the fitting recess 35h.
To fit the cowling panel 35 to the body frame 1
The first stay 55 is supported.

At the same time, the fixing pin 61 on the down tube 22 side is inserted and fitted into the damper member 62 of the body front under 50 so that the body front under 50 is attached to the bracket 6 of the body frame 11.
0 to support the cowling panel 3
The position of the rear end edge 35g of the fifth fuel tank 18 with respect to the fuel tank 18 can be adjusted.

Next, the cowling panel 35 is fixed to the fixing bracket 18b of the fuel tank 18 with the screw 52 with reference to the fuel tank 18.

As described above, the headlight 36 and the like are attached to the cowling panel 35 in advance, and the cowling panel 35 and the like are attached to the vehicle body frame 11 so as to be adjustable in position. Even if the mounting position is displaced from the mounting position of the cowling panel 35 with respect to the fuel tank 18, the cowling panel 35 can be mounted with the fuel tank 18 as a reference.

By doing so, it is possible to prevent the headlight 36, the cowling panel 35 and the fuel tank 18 from being displaced.
The appearance quality can be ensured, and mounting can be performed easily.

The rubber damper members 57, 57, other than the mounting portions of the cowling panel 35 and the like to the fuel tank 18, are provided.
Since it is attached by using 62, vibration can be absorbed and generation of chattering noise and the like can be suppressed.

In the above embodiment, the front window panel 39 other than the headlight 36, the body front under 50, and the like are attached to the cowling panel 35.
And body front under 50 are cowling panel 3
5 can be attached to the vehicle body frame 11.

[0043]

As described above, according to the present invention, the headlight is attached to the cowling panel in advance, and the cowling panel is attached to the body frame so as to be adjustable in position. Even if the mounting position of the cowling panel with respect to the vehicle body frame and the mounting position of the cowling panel with respect to the fuel tank are misaligned, the cowling panel can be mounted with reference to the fuel tank.
