[0014]
4 is a front view, FIG. 5 is a top view of the front part of the vehicle body, FIG. 6 is a side view of a main part of the same part, FIG. 7 is an assembly view of the same part, and FIG. .
[0015]
6 to 8, the front cowl 5 is supported by a head pipe 31 provided at the front end of the main frame 8 via a cowl stay 30 (see FIGS. 6 and 7).
[0016]
The cowl stay 30 includes a box-shaped light box 32, a side arm 33 extending diagonally upward and backward from the light box 32 in a pair to the left and right, an oil cooler stay 34 protruding laterally from a side surface of the light box 32, and a light box 32. And a center arm 35 extending rearward along the center of the vehicle body from the rear surface of the vehicle, and is formed as a pair of a suitable resin.
[0017]
A bolt 37 passed through a mounting hole 36 formed in the front center portion of the front cowl 5 is fastened to the mounting portion 32a formed in the front upper center of the light box 32 (FIG. 7).
[0018]
The light box 32 has a housing part 38 opened forward, and the headlight 6 fitted therein faces a light hole 40 formed in the front center part of the front cowl 5 .
[0019]
A harness 39 is wired in the accommodation section 38 of the light box 32 (FIG. 8), and the harness 39 passes through the hollow center arm 35 and reaches the rear end.
[0020]
The oil cooler stay 34 is provided with a mounting hole 34a, and a bolt 7b passing therethrough is fastened to a bracket 7a formed on the upper part of the oil cooler 7 (FIG. 8), so that the oil cooler stays through the oil cooler stay 34. 7 is attached to the side of the cowl stay 30.
[0021]
