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

BACKGROUND OF THE INVENTION Conventionally, there are straddle-type vehicles that use a fuel tank cover to cover at least the upper part of a fuel tank.

However, in the saddle type vehicle, it is generally not easy to position and fix the fuel tank cover in a predetermined position, and if the fuel tank cover is displaced after it has been fixed, There was a problem that it became unsightly.

The present invention has been made in view of the above-mentioned circumstances, and provides a fuel tank cover mounting structure for a straddle-type vehicle that allows easy positioning and prevents the cover from shifting after being fixed. The purpose is to provide.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a fuel tank cover for a straddle-type vehicle in which at least the upper part of the fuel tank located in front of the seat is covered by a fuel tank cover. In the mounting structure, a bracket formed by symmetrically bending into a step shape is attached to the rear end surface of the fuel tank, the fuel tank cover is brought into contact with the middle part of the bracket, and the sheet is attached to the top of the bracket. The front ends of the two are brought into contact with each other.

[0006]

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

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

[0008] Here, the fuel tank cover 3 consists of a center cowl 5 and two side cowls 6, 6.

[0009] The bracket 4 is formed by being bent symmetrically in two stages, with the center serving as a top portion 4a, and the first stage on the left and right serving as midsections 4b, 4b.

Upright wall portions 4c, 4c are provided between the top portion 4a of the bracket 4 and its left and right middle portions 4b, 4b.

The bracket 4 has left and right end portions 4d, 4
It is welded and fixed to the fuel tank 2 at d.

The fuel tank cover 3 is formed to be large enough to cover substantially the top surface, both 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, extending pieces 6a, 6 are provided at the inner end portions of the side cowls 6, 6, respectively, with the inner ends thereof facing inward.
a are provided respectively.

In this embodiment, first, each of the extending pieces 5a, 5a of the center cowl 5 is attached to the vertical wall portion 4c of the bracket 4.
, 4c, the midsections 4b, 4 of the bracket 4.
Put it on b. As a result, the extending pieces 5a, 5a of the center cowl 5 are
The bracket 4 allows easy positioning.

Next, the extending pieces 6a, 6a of the left and right side cowls 6, 6 are attached to the vertical wall portion 4c of the bracket 4, respectively.
, 4c, respectively, and place it on the extending pieces 5a, 5a of the center cowl 5. Thereby, the extending pieces 6a, 6a of the left and right side cowls 6, 6 can be easily positioned by the bracket 4.

Next, in this state, the extending pieces 5a, 5a of the center cowl 5 and the extending pieces 6a, 6a of the left and right side cowls 6, 6 are attached to the middle part 4b of the bracket 4 using the bolts 7, 7. , 4b, respectively. by this,
The installation of the fuel tank cover 3 is completed.

Furthermore, in this embodiment, the seat 8 of the vehicle 1
The front end 8a of the front end 8a is brought into contact with the top 4a of the bracket 4 via a seat rubber cushion 9 provided at the bottom thereof.

The seat rubber cushion 9 is fixed in advance to a reinforcing member 8b provided at the bottom of the seat 8.

[0020] Thus, the bracket 4 serves to position, support and fix the fuel tank cover 3, and also serves to support the front end 8a of the seat 8, thereby increasing the efficiency of parts utilization.

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

In this embodiment, locking pieces 5b, 5b are provided upright on the extending pieces 5a, 5a of the center cowl 5.

As a result, the extending pieces 6 of the left and right side cowls 6, 6 are attached to the locking pieces 5b, 5b of the center cowl 5.
By bringing a and 6a into contact with each other, the side cowl is positioned.

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

In this embodiment, the bracket 4 is formed in one step, and the inclined portions 6 are provided at the inner ends of the left and right side cowls 6, 6 corresponding to the vertical wall portions 4c, 4c of the bracket.
b, 6b are provided, and extending portions 6a, 6a are provided at the tips of the inclined portions.
We are trying to provide each.

As a result, the extending pieces 5a, 5a of the center cowl 5 are first placed on the top portion 4a of the bracket 4, and then the inclined portions 6b, 6b of the left and right side cowls 6, 6 are placed on the vertical wall portion 4c of the bracket 4. , 4c, and the extending pieces 6a, 6a of the center cowl 5 are brought into contact with the extending pieces 5a, 5a of the center cowl 5.
Put it on top.

At this time, the inclined portions 6b, 6b of the left and right side cowls 6, 6 are aligned with the vertical wall portions 4c, 4 of the bracket 4.
c, and in this state, by bringing the outer surfaces of the extending pieces 5a, 5a of the center cowl 5 into contact with the inclined parts 6b, 6b of the left and right side cowls 6, the center cowl 5 is positioned. is also positioned.

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

[0029]

As explained above, according to the fuel tank cover mounting structure for a straddle-type vehicle according to the present invention, when fixing the fuel tank cover, the fuel tank cover is brought into contact with the midsection of the bracket. Since the positioning is performed in advance by moving the object, the positioning can be performed easily and quickly.

Furthermore, since the fuel tank cover is positioned and fixed in contact with the bracket, it is possible to reliably prevent the fuel tank cover from shifting with respect to the fuel tank.

Furthermore, according to the present invention, the bracket can be used not only to position the fuel tank cover, but also to support the front end of the seat, increasing the efficiency of parts utilization and reducing the weight of the vehicle body. You can also try it out.
