DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank cover mounting structure for a saddle type vehicle.

[0002]

2. Description of the Related Art Conventionally, there is a straddle-type vehicle in which a fuel tank cover is used to cover at least an upper portion of a fuel tank.

However, in the saddle-ride type vehicle, it is generally not easy to position and fix the fuel tank cover at a predetermined position, and when the fuel tank cover is displaced after the fuel tank cover is fixed. Had a problem that it became unsightly. Therefore, a prior art (JP-A-59-192683) is known in which a rear end portion of a fuel tank cover is extended rearward and fixed. However, according to such prior art, since the seat is provided so as to cover the rear portion of the fuel tank, a load applied to the seat is applied to the fuel tank cover, and the fuel tank cover is deformed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a fuel tank cover mounting structure for a saddle-ride type vehicle, which can easily be positioned and prevent the position from being shifted after being fixed. The purpose is to provide.

[0005]

According to the present invention, in order to achieve the above object, a fuel tank cover for a saddle type vehicle in which a fuel tank positioned in front of a seat is covered at least with a fuel tank cover. In the mounting structure, a bracket formed by bending stepwise symmetrically to the left and right is mounted on the rear end face of the fuel tank, and the fuel tank cover is brought into contact with the middle abdomen of the bracket, and the seat is mounted on the top of the bracket. A gap is formed between the fuel tank cover and the front end of the seat such that the front end of the seat abuts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fuel tank cover mounting structure for a straddle-type vehicle according to the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 to 5 show a first embodiment of the present invention. In the present embodiment, a bracket 4 for positioning the fuel tank cover 3 is attached to the rear end face 2a of the fuel tank 2 of the saddle type two-wheeled vehicle 1.

Here, the fuel tank cover 3 is composed of a center cowl 5 and two side cowls 6,6.

[0009] The bracket 4 is formed to be bilaterally symmetrically bent in two steps in a stepwise manner. The center of the bracket 4 is a top portion 4a, and the first left and right stages are middle abdomen portions 4b, 4b.

Standing walls 4c, 4c are provided between the top 4a of the bracket 4 and the middle portions 4b, 4b on the left and right sides thereof.

The bracket 4 is welded and fixed to the fuel tank 2 at its left and right ends 4d, 4d.

The fuel tank cover 3 is formed large enough to cover substantially the upper surface, the left and right side surfaces, and the rear surface of the fuel tank 2.

A pair of extending pieces 5a, 5a are provided at the rear end of the center cowl 5 toward the rear.

Further, extension pieces 6a, 6a are also provided at the inner ends of the side cowls 6, 6, respectively, facing inward.

In this embodiment, first, the extension pieces 5a, 5a of the center cowl 5 are placed on the middle abdomen 4b, 4b of the bracket 4 while being in contact with the upright walls 4c, 4c of the bracket 4.
Thus, the extension pieces 5a, 5a of the center cowl 5 are easily positioned by the bracket 4.

Next, the extension pieces 6a, 6a of the left and right side cowls 6, 6 are respectively brought into contact with the upright walls 4c, 4c of the bracket 4, respectively, while the extension pieces 5a, 5c of the center cowl 5 are held.
Place on 5a. As a result, the left and right side cowls 6, 6
The extension pieces 6a, 6a are easily positioned by the bracket 4.

Then, in this state, the extension pieces 5a, 5a of the center cowl 5 and the extension pieces 6a, 6a of the left and right side cowls 6, 6 are attached to the middle abdomen 4 of the bracket 4 using the bolts 7, 7.
b and 4b respectively. Thus, the mounting of the fuel tank cover 3 is completed.

Further, in this embodiment, the seat 8 of the vehicle 1 is
Of the bracket 4 is in contact with a top portion 4a of the bracket 4 via a seat rubber cushion 9 provided below the front end portion 8a. As a result, a gap X is formed between the rear surface of the fuel tank cover 3 and the front end 8a of the seat 8.

The seat rubber cushion 9 is fixed in advance to a reinforcing member 8b disposed below the seat 8.

Thus, the bracket 4 not only serves to position, support and fix the fuel tank cover 3 but also serves to support the front end 8a of the seat 8, thereby improving the efficiency of use of components.

FIG. 6 shows a second embodiment of the present invention, in which components corresponding to those shown in FIG. 5 are denoted by the same reference numerals.

In this embodiment, the extension piece of the center cowl 5
Locking pieces 5b, 5b are erected on 5a, 5a.

Thus, the locking pieces 5b, 5b of the center cowl 5 are attached to the extension pieces 6a, 6a of the left and right side cowls 6, 6.
The side cowl is positioned by bringing the side cowl into contact.

FIG. 7 shows a third embodiment of the present invention, in which components corresponding to those shown in FIG. 5 are denoted by the same reference numerals.

In this embodiment, the bracket 4 is formed in one step, and the inclined portions 6b, 6b are formed on the inner ends of the left and right side cowls 6, 6 corresponding to the upright walls 4c, 4c of the bracket.
And the extending portions 6a, 6a are provided at the tip of the inclined portion, respectively.

As a result, the extension pieces 5a, 5a of the center cowl 5 are first placed on the top 4a of the bracket 4, and thereafter, the inclined portions 6b, 6b of the left and right side cowls 6, 6 are attached to the bracket 4.
The extension pieces 6a, 6a are placed on the extension pieces 5a, 5a of the center cowl 5 while being in contact with the upright wall portions 4c, 4c.

At this time, the left and right side cowls 6, 6 are positioned by their inclined portions 6b, 6b abutting against the vertical walls 4c, 4c of the bracket 4, and in this state, the extension pieces 5a of the center cowl 5 are extended. , 5a are brought into contact with the inclined portions 6b, 6b of the left and right side cowls 6, 6, so that the center cowl is also positioned.

After that, the positioned center cowl 5 and left and right side cowls 6, 6 are fixed to the bracket 4 using bolts 7.

[0029]

As described above, according to the fuel tank cover mounting structure for a saddle-ride type vehicle according to the present invention, when the fuel tank cover is fixed, the fuel tank cover abuts on the middle part of the bracket. Since the positioning is performed in advance, the positioning can be performed easily and quickly.

Further, since the fuel tank cover is brought into contact with the bracket and positioned and fixed,
It is possible to reliably prevent the fuel tank cover from shifting with respect to the fuel tank. Furthermore, since the front end of the seat is brought into contact with the top of the bracket to form a gap between the fuel tank cover and the front end of the seat, the load of the seat is applied to the fuel tank cover. There is no.

Further, according to the present invention, not only can the bracket be used for positioning the fuel tank cover, but also the front end of the seat can be supported, so that the use efficiency of parts can be increased and the weight of the vehicle body can be reduced. You can also plan.
