Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric component mounting structure for a motorcycle.

[0002]

2. Description of the Related Art Recently, some motorcycles have electronically controlled engines and instruments, and require various electric components. As shown in FIG. 5, some electric components, such as the igniter 1, are not shown in the upper part of the rear fender 4 (below the operating seat 5) or in the seat rail 6 located behind the mounting bracket 3 of the fuel tank 2. It is generally mounted with screws or the like through a spacer or the like.

[0003]

However, it is difficult to form a storage space for storing documents and small articles between the driving seat and the rear fender at the mounting position of the conventional electric component.

In addition, the conventional method of mounting electrical components is not preferable because the number of parts increases and vibration of the vehicle body is easily transmitted to the electrical components.

Further, the space surrounded by the air cleaner arranged at the lower portion of the fuel tank, the fuel tank mounting bracket, the battery arranged at the front part of the rear fender, and the seat rail is a dead space.

The present invention has been made in view of the above circumstances, and provides an electric component mounting structure for a motorcycle, which can effectively use dead space, can be mounted with a small number of parts, and is less likely to transmit vibration of the vehicle body. With the goal.

[0007]

In order to solve the above-mentioned problems, an electric component mounting structure for a motorcycle according to the present invention is provided.
As described in claim 1, in a motorcycle equipped with an electrical component such as an igniter, an electrical component mounting rib is integrally or integrally formed at a rear portion of an air cleaner arranged on an upstream side of an engine, and the electrical component mounting rib is formed. The above-mentioned electrical equipment is attached to the rib.

[0008]

In the present invention having the above-mentioned structure, the electric component mounting rib is formed integrally or integrally with the rear portion of the air cleaner arranged on the upstream side of the engine of the motorcycle equipped with the electric component such as the igniter. Since the electrical component is attached to the component mounting rib, the dead space surrounded by the air cleaner, the fuel tank mounting bracket, the battery, and the seat rail can be effectively used, and the electrical component can be mounted with a small number of components. Moreover, since the electrical components are not attached to the rear fender or the seat rail, the vibration of the vehicle body is hard to be transmitted.

The cleaner case 17a of the air cleaner 17 is formed by molding a thermoplastic resin, for example. In front of the engine 13, a radiator 18a and a cooling water pipe 18 that constitute an engine cooling system 18 are provided.
b is arranged.

A head pipe 19 is provided in front of the body frame 12, and a steering mechanism 20 is provided on the head pipe 19. The steering mechanism 20 includes a front fork 2 that rotatably supports a front wheel 21.
2, a handlebar 23, an instrument unit 24, a front fender 25, and the like are provided, and the handlebar 23 steers the front wheel 21 so as to be rotatable left and right.

By the way, the body frame 12 of the present embodiment.
Is the strength member of the engine 13, that is, the body frame 1.
It is a diamond type frame used as a part of 2. The body frame 12 is, for example, a twin-tube type body, and has a pair of left and right main frames 26 that extend rearward in the left-right direction immediately after the head pipe 19 and extend rearward in parallel with each other. A pair of left and right seat rails 2 extending rearward from the vicinity of the rear portion
And 7. A fuel tank 28 is installed on the main frame 26, and an opening / closing or removable operation seat 29 is installed on the seat rail 27.

On the other hand, a swing arm 31 is pivotally attached to a pivot shaft 30 which is provided at a lower center of the body frame 12 so as to swing around the pivot shaft 30, and a rear wheel 32 is rotated at a rear end of the swing arm 31. Freely supported.
A rear shock absorber 33 and a plurality of links 34 are provided on the base end side of the swing arm 31, and these swing arm 31 and rear shock absorber 33 are provided.
A rear suspension mechanism 35 is composed of the link 34. A rear fender 36 is provided above the rear wheel 32.
Is placed in front of the rear fender 36.
7 is placed.

FIG. 2 is an enlarged side view of the motorcycle 11 centering around the air cleaner 17, and FIG.
FIG. 4 is a view on arrow I, and FIG. 4 is a view on arrow IV in FIG.

As shown in FIG. 2, the cleaner case 17a of the air cleaner 17 is fixed to the air cleaner mounting bracket 38 provided on the seat rail 27 by a bolt, for example, via a vibration isolator (not shown). In addition, the fuel tank 28
The rear end portion is also attached to the fuel tank mounting bracket 39 provided on the seat rail 27 via the vibration isolator 40, for example, the bolt 4
