Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a synthetic resin fuel tank to a motorcycle.

Conventional installation devices of this type are, for example, disclosed in U.S. Pat.
As in the invention described in Japanese Patent No. 765, the fuel tank is fixed to the vehicle body frame with a mounting member/supporting member having a buffer member and a set screw.

Synthetic resin fuel tanks have a tendency to swell due to gasoline soaking in after long-term use, and the conventional installation described above does not allow the tank to move in the front, back, left, or right directions. There were some inconveniences such as temporary deformation.

The purpose of this invention is to eliminate this inconvenience, and when fixing a synthetic resin fuel tank to the body frame of a motorcycle using metal fittings and set screws, the stop part is provided as a relief against deformation due to swelling of the fuel tank. The configuration allows for

The embodiments shown in the drawings will be specifically described below.

1 is the body frame of a motorcycle, 2 is a fuel tank integrally molded from synthetic resin, and 3 is the fuel tank 2 attached to the body frame 1.
The mounting is done using a metal fitting, for example L-shaped, with two bolt holes 4 and 5 formed on one side (horizontal side) 3a, one of which is an elongated hole, and the other side (hanging side) 3b. A cylindrical elastic grommet 7 made of rubber or the like is attached to the central hole 6 of the grommet.

A slide collar 8 is provided on the inner surface of this cylindrical elastic grommet 7.
are integrated.

To attach the fuel tank 2 to the vehicle body frame 1, as shown in FIG. 4, 5) 9.10 into fuel tank 2
11. Attach by screwing into 12.

In this case, an elastic ring 13 made of rubber or the like is fitted onto the bolt 10 passed through the elongated hole 5, and the elastic ring 13 is pressed against the lower surface of one side 3a of the metal fitting 3 via a pressing ring 14.

Next, as shown in FIG. 3, the sliding guide tube 15, which is longer than the slide collar, is passed through the slide collar 8.
A bolt 16 longer than the sliding guide tube 5 is passed through the hole 17 of the vehicle body frame 1, and then tightened and fixed with a nut 18.

In the figure, reference numeral 19 denotes a stopper plate which is inserted into the bolt 16 and interposed between the washer 20 and the sliding guide tube 15, and can be omitted if it is also used as the washer 20.

In the case of this installation, since the device has the above-mentioned configuration, in case of deformation in the front-rear direction of the vehicle body due to swelling of the fuel tank, the bolt 10 must be tightened so that the bolt 10 escapes in the left-right direction in FIG. 2, that is, in the front-rear direction of the vehicle body. Moving.

In addition, when the vehicle body is deformed in the width direction, the elastic grommet 7 smoothly escapes along the sliding guide tube 15 via the slide collar 8 in the axial direction of the sliding guide tube, that is, in the width direction of the vehicle body.

Therefore, the above-mentioned disadvantages caused by swelling and deformation are well eliminated, and the installation of a synthetic resin fuel tank is extremely effective as a device.

Further, since the elastic grommet 7 functions to absorb vibrations of the vehicle body and impact force from the outside, the fuel tank can be stably mounted and supported.

In the figure, 21 is an engine, 22 is a seat, 23 is a head pipe, and 24 is a front fork.
