In the cross-sectional view of FIG. 5, the tank center portion 75 bulges in a curved manner toward the top and bottom of the vehicle. The capacity of the tank center portion 75 is larger than the capacity of the tank side portions 76 (for example, the capacity of one of the pair of left and right tank side portions 76). In the cross-sectional view of FIG. 6, the tank center portion 75 extends from above the air cleaner 50 toward the rear and lower side of the air cleaner 50 while being curved.

Note that the electrical component fixing portion 57 is a region where the electrical component 60 is arranged, but this region may be a region near the periphery to which the electrical component 60 is fixed.

For example, if the case side portion 76 of the air cleaner 50 is made larger than the case center portion 55 in order to secure the capacity of the air cleaner 50, the following problems occur. When the connecting tube 59 is arranged in the case center part 55 of the air cleaner 50, it may be difficult to supply air from the case side part 56 of the air cleaner 50 to the engine 11. Note that the case center portion 55 may be within the width range of the connecting tube 59.

<Electrical parts>
For example, the electrical component 60 is a coupler for a combination switch (main switch). The combination switch functions as an ignition switch and a steering lock. Current is supplied to the combination switch via a harness from a battery (not shown) provided on the vehicle body side.

For example, the combination switch is provided at the front of the vehicle. A cylinder lock (not shown) is provided on the top of the combination switch. For example, with the ignition key inserted into the cylinder lock, the ignition key is rotated left and right. This makes it possible to turn the ignition ON/OFF and to lock and unlock the rotation of the front wheel steering system (e.g., front wheels, left and right front forks, steering stem, bar handle, etc.) around the head pipe 21. .

The electrical component 60 is arranged 49 between the fuel tank 7 and the air cleaner 50. In the present embodiment, the central portion of the electrical component 60 is disposed between the fuel tank 7 and the air cleaner 50 at a side portion 49 in the vehicle width direction. The electrical component 60 is arranged outside the center line of the fuel tank 7 and air cleaner 50. In the present embodiment, all of the electrical components 60 are arranged outward in the vehicle width direction from the vehicle body left-right center line CL (the center position of the vehicle in the vehicle width direction). In the tank cover attached state shown in FIG. 1, the tank cover 41 is formed to expose the upper surface (fuel cap 71) of the fuel rank 7 and cover the space 49 between the fuel tank 7 and the air cleaner 50 from the side of the vehicle. ing. In the tank cover attached state, the electrical component 60 is covered by the air cleaner 50, the fuel tank 7, and the tank cover 41.

In a top view of FIG. 3, the electrical component 60 overlaps the fuel tank 7 and the air cleaner 50.

In a top view of FIG. 3, the electrical component 60 is disposed inward in the vehicle width direction from the outer end of the case side portion 56 of the air cleaner 50 in the vehicle width direction (the outer end of the electrical component fixing portion 57).

<Electrical component support section>
As shown in FIG. 7, the electrical component 60 is supported by an electrical component support section 61 so as to be positionable with respect to the electrical component fixing section 57. As shown in FIG. The electrical component support portion 61 is provided on a flat surface of the electrical component fixing portion 57 of the air cleaner 50 . Therefore, it is easier to position the electrical component 60 compared to the case where the electrical component support portion 61 is provided on the curved surface of the electrical component fixing portion 57 of the air cleaner 50.

For example, the electrical component support portion 61 includes an electrical component support stay 62 that supports the electrical component 60 and a bolt 63 that fixes the electrical component support stay 62 to the air cleaner 50. For example, the electrical component support stay 62 has a plurality of through holes (not shown) through which bolts 63 can be inserted. For example, the electrical component fixing portion 57 of the air cleaner 50 has a plurality of female screw portions (not shown) into which bolts 63 can be screwed. The plurality of female screw portions are arranged at intervals from each other in the electrical component fixing portion 57.

For example, the electrical component 60 can be supported by the electrical component fixing part 57 by inserting the bolt 63 into the through hole of the electrical component support stay 62 and screwing it into the female thread part of the electrical component fixing part 57. For example, the electrical component 60 is fixed to the electrical component fixing portion 57 with a plurality of (two in the example of FIG. 7) bolts 63 via an electrical component support stay 62. For example, by changing the position of the through hole of the electrical component support stay 62 with respect to the female screw portion of the electrical component fixing portion 57, the installation position of the electrical component 60 with respect to the electrical component fixing portion 57 can be changed.

<Electrical equipment cover>
