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.

[0002]

2. Description of the Related Art In a conventional fuel tank cover mounting structure for a motorcycle or the like, a hole 14 is provided in a fuel tank cover 13 corresponding to a mounting portion 12 of a tank cap 11 of a fuel tank 10 as shown in FIG. ing. Then, the fuel tank cover was attached to the fuel tank 10 while adjusting the position of the fuel tank cover 13 so that the hole 14 coincided with the tank cap attaching portion 12 of the fuel tank 10.

[0003]

By the way, in the conventional fuel tank cover mounting structure, the fuel tank cover 13 is fixed to the extending portion 15 extending from the fuel tank. The extended portion 15 is generally located away from the hole 14.

[0004] Therefore, it is difficult to align the hole 14 of the fuel tank cover 13 with the fuel tank cap mounting portion 12 of the fuel tank 10, and the upper surface of the fuel tank cover 13 and the fuel tank cap mounting portion 12 are mounted. There was a problem that a step was formed between the fuel tank cap 11 and the upper surface.

[0005] Therefore, the mounting position of the fuel tank cover 13 must be changed so that such misalignment and steps are eliminated.
Adjustment may be made at the time of installation, but such adjustment work is not easy and requires time and effort.

Although it is conceivable to increase the precision of the components in advance so as not to cause the above-described misalignment or step, there is a disadvantage that the production cost is increased, and this has not been a good solution.

The present invention has been made in view of the above circumstances, and a fuel tank cover mounting structure capable of easily preventing misalignment and a level difference, thereby enabling a fuel tank cover to be mounted quickly. The purpose is to provide.

[0008]

According to the present invention, in order to achieve the above object, a hole provided in a fuel tank cover is aligned with a tank cap mounting portion of the fuel tank, and the fuel tank cover is connected to the fuel tank. In the fuel tank cover mounting structure adapted to be mounted, a guide protrudes from the tank cap mounting portion of the fuel tank, and a cover receiving portion is provided near the guide, and on the other hand, a peripheral portion of the hole of the fuel tank cover is provided. Protrusion is provided downward, and when the fuel tank cover is mounted on the fuel tank, the fuel tank cover is positioned in a substantially horizontal direction by abutting on the side surface of the guide, And when the above-mentioned convex part contacts the above-mentioned cover receiving part, Serial substantially vertical positioning of the fuel tank cover is configured to be made.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fuel tank cover mounting structure according to an embodiment of the present invention.

FIGS. 1 to 6 show an embodiment of the present invention. In the fuel tank cover mounting structure of this embodiment, a hole 5 is provided in the fuel tank cover 4 corresponding to the tank cap mounting portion 3 of the fuel tank 2 of the motorcycle 1.

On the tank cap mounting portion 3 of the fuel tank 2, a cylindrical guide 6 protrudes.

An annular cover receiving portion 7 is provided around a lower portion of the cylindrical guide 6 of the tank cap mounting portion 3 of the fuel tank 2.

On the other hand, a plurality of two types of convex portions 8 and 9 are provided on the peripheral portion 4a of the hole 5 of the fuel tank cover 4 downward.

The protruding portion 8 is formed to have a relatively low height, and is formed along the entire periphery of the peripheral portion 4a of the hole 5 so that the hole 5 of the fuel tank cover 4 matches the guide 6 of the fuel tank 2. It is provided annularly across.

On the inner peripheral surface of the projection 8, a plurality of projections 8 are located in a straight line with the projection 9 toward the center of the hole 5.
a is provided.

The plurality of projections 9 are formed radially continuously from the projections 8, and the fuel tank cap mounting portion 3 at the peripheral edge 4 a of the hole 5 of the fuel tank cover 4 is formed.
It is provided slightly larger so as to have a height sufficient to determine the height with respect to.

In FIG. 2, a two-dot chain line indicates a tank cap of the fuel tank 2.

According to the present embodiment, the projection 8 of the fuel tank cover 4, that is, the plurality of projections 8a are substantially in contact with the outer peripheral wall of the guide 6 of the fuel tank 2, so that the fuel tank cover 4 Substantially horizontal positioning is automatically performed.

When the plurality of projections 9 of the fuel tank cover 4 abut on the cover receiving portion 7 of the fuel tank 2, positioning of the fuel tank cover in the substantially vertical direction is automatically performed.

As a result, the work of aligning the hole 5 of the fuel tank cover 4 with the tank cap mounting portion 3 of the fuel tank 2 becomes unnecessary, and the work of adjusting the height at the peripheral edge 4a of the fuel tank cover 4 becomes unnecessary. Thus, the operation of attaching the fuel tank cover can be performed easily and quickly.

The number and shape of the projections 8 and 9 provided on the peripheral portion 4a of the fuel tank cover 4 are not particularly limited, and the shape of the fuel tank cap mounting portion 3 of the fuel tank 2 and the like are taken into consideration. May be determined appropriately.

In the above embodiment, two kinds of projections 8 and 9 are continuously provided on the peripheral portion 4a of the hole 5 of the fuel tank cover 4, but the present invention is not limited to this, and the two projections are independently provided. May be provided.

Further, in the present invention, one annular convex portion may be provided so as to perform both the positioning in the substantially horizontal direction and the substantially vertical direction of the peripheral portion 4a of the fuel tank cover, and the annular shape is not annular. A large number of projections may be provided and the positioning may be performed.

[0024]

As described above, according to the fuel tank cover mounting structure of the present invention, a guide is projected from the tank cap mounting portion of the fuel tank, and a cover receiving portion is provided near the guide. On the other hand, a convex portion is provided downward at the peripheral portion of the hole of the fuel tank cover, and when the fuel tank cover is attached to the fuel tank, the convex portion contacts the side surface of the guide. The fuel tank cover is positioned in a substantially horizontal direction, and the fuel tank cover is positioned substantially vertically by contacting the convex portion with the cover receiving portion. The hole does not shift, and the step does not occur even in the peripheral part

Therefore, when mounting the fuel tank cover, the work of adjusting the position of the fuel tank cover becomes unnecessary, and the work of mounting the fuel tank cover can be performed easily and quickly.

Further, since the position adjusting operation of the fuel tank cover is no longer necessary, it is not necessary to increase the accuracy of the parts of the fuel tank and the fuel tank cover more than necessary. Therefore, it can be implemented without significantly increasing the manufacturing cost, and is economical.
