Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fuel tank for a motorcycle (including a three-wheeled motor vehicle), and particularly relates to the attachment of the fuel tank.

Prior Art The fuel tank of a motorcycle is usually arranged along the shape of the upper body frame, and when a fuel tank is arranged below the fuel tank, the upper body frame, the engine It is often difficult to secure enough space to easily operate the fuel tank due to various auxiliary equipment and obstacles.

As a countermeasure, there is a fuel tank attached to the side plate of the fuel tank (Japanese Unexamined Patent Publication No. 58-202175), but although it improves operability, it increases the number of piping parts in the fuel tank and increases the number of parts. This complicates fuel tank production and increases production costs.

Furthermore, even if the same fuel tank is attached to the bottom plate, not only the above-mentioned problems occur, but also the fact that the operating lever of the fuel tank does not protrude makes it difficult to see and operate.

Problems to be Solved The aim of the present invention is to improve the visibility and operability of the fuel pot and to simplify the attachment of the fuel pot to the fuel tank.

Means and Effects for Solving the Problems The present invention provides for a fuel pot to be mounted above the lower end of the outer periphery of the fuel tank on a bottom plate forming the bottom of the fuel tank, and a portion located outside of the mounting position of the fuel pot to be attached to the bottom plate. A recess is formed upwardly from a lower end of the outer peripheral wall of the fuel tank, and an operating lever of the fuel pot is located above the lower end of the outer peripheral wall of the fuel tank and disposed inside the recess, and the recess This is a fuel tank for a motorcycle in which the operating space for the operating lever is the operating space for the operating lever.

An upwardly recessed recess leading to the bottom plate is provided at the lower end of the outer circumferential wall of the fuel tank, and the lever of the fuel handle attached to the bottom plate is operated from the recess. The operating lever can be operated at the recessed position without being obstructed by various existing members.

The operating position of the operating lever can be easily confirmed from the side of the fuel tank, making it easy to operate.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

FIG. 1 shows a motorcycle 1 equipped with a cowling C, in which a fuel tank 4 has a front and rear V-type engine E.
It is located above the upper vehicle body frames 2 and 3 and is arranged along the upper vehicle body frames 2 and 3.

The rear part of the fuel tank 4 is covered by the front part of the seat S.

At the rear of the fuel tank 4, a pair of left and right recesses 5 and 6 are formed at the lower end of the outer circumferential wall 4a and are recessed upward, communicating with the bottom plate 7 side of the fuel tank.

Further, inside the recesses 5 and 6, fuel pots 9 are screwed and fixed to a pair of left and right flanges 8 attached to the bottom plate 7, respectively (see FIGS. 1 to 3 above). , FIG. 2 is an enlarged view of the fuel tank 4, and FIG. 3 is a bottom view thereof, with one fuel tank omitted).

The fuel pot 9 is shown in FIGS. 4 to 6 (FIG. 5 is a view taken along the - arrow in FIG. 4, and FIG.
As shown in (which is a cross-sectional view taken along the - line in the figure),
It includes a fuel pipe connecting tube 13 and passages 11,1.
2 and a small body 10 having another passage (not shown) communicating with the fuel pipe connecting cylinder 13, and a first strainer cylinder 14 communicating with the passages 11 and 12,
The main body includes a second strainer cylinder 15, a rotating body 16 having an arcuate groove 17, and a cross-shaped operation lever 18 screwed onto the rotating body 16.

When the operating lever 18 is rotated and set to the OFF position, the other passages communicating with the fuel pipe connecting cylinder 13 are placed in a state where they are not communicated with any of the passages 11 and 12, and when set to the ON position, the other passages are placed in a state where they are not communicated with any of the passages 11 and 12. The passage 11 communicates with the passage 11 through the groove 17, and when set to the RES (reserve) position, the other passage 12 communicates with the passage 12 through the groove 17.

The present embodiment is constructed as described above, and when driving, the operating lever 18 is set to the ON position.
When parking, the operating lever 18 is set to the OFF position, but when the fuel level in the fuel tank 4 drops to level L (see Figure 6), the operating lever 18 is set to the RES position. Set to .

Note that when the operating lever 18 is in the ON position,
The fuel in the fuel tank 4 is transferred to the first strainer tube 14
However, when the operating lever 18
When in position, fuel is discharged through the second strainer tube 15.

Therefore, the operating lever 18 can be operated by inserting a finger into the bottom plate 7 side from the recesses 5 and 6 formed at the lower end of the outer circumferential wall 4a of the fuel tank 4. The parts are not a problem.

Note that the operating lever 18 can be easily seen from the recesses 5 and 6, and the operating lever 18 can be easily moved if the length a of the recesses 5 and 6 is made large enough to allow at least two fingers to be inserted.

In addition, as in this embodiment, the fuel pot 9 is connected to the bottom plate 7.
Compared to the case where the fuel pot is attached to the side plate of the fuel tank, there is no need for piping inside the fuel tank, and the number of parts can be reduced and ease of assembly can be improved.

In this embodiment, a pair of fuel pots 9 are provided, one on the left and one on the right, but in a normal model, only one is provided, and one recess may be formed accordingly.

In addition, if the fuel pot mounting position differs depending on the model, a recess may be formed at an arbitrary location on the lower end of the outer circumferential wall of the fuel tank (for example, at an intermediate position in the longitudinal direction, at the rear end, etc.).

Further, as the operating lever, a fuel tip that is structured to swing in the horizontal direction along the planar shape of the recess can also be used.

Effects of the Invention As is clear from the description of the embodiments, in the fuel tank of the present invention, a recessed portion communicating with the bottom plate is provided at the lower end of the outer circumferential wall, and the operating lever of the fuel handle attached to the bottom plate is operated using the recessed portion. Since the control lever can be easily operated regardless of the arrangement of other members located below the fuel tank, the control lever for the fuel handle is attached to the side plate of the fuel tank. Compared to the case, the piping is simplified, and there are various advantages such as a reduction in the number of parts, improvement in assembly work efficiency, and cost reduction.

In addition, the operating position of the control lever can be easily seen from the fuel tank, making it easy to operate.
