Description

[Detailed description of the invention] The present invention relates to an improvement of a fuel tank mounting device.
In particular, the present invention relates to a fuel tank mounting device that allows the fuel tank to be easily positioned and mounted.

Generally, a fuel tank is attached to an engine body using attachment means such as a tank bracket and a band.

As such a fuel tank mounting device, there is a prior art described in Japanese Utility Model Application Publication No. 113715/1983,
In order to prevent damage to the fuel tank mounting band, this prior art is intended to avoid local contact between the band and the tank and to tighten the tank with the entire band, thus preventing damage to the fuel tank mounting band. No particular consideration is given to positioning, and there are disadvantages such as the tank installation work being complicated and troublesome.

Furthermore, in the prior art shown in FIG. 1, rattling after the fuel tank is installed is prevented by interposing a rubber band, which is a cushioning material, on the contact surface between the tank bracket and band and the fuel tank. . Particularly in this prior art, an engagement wall 2 is provided upright on the peripheral edge of the opening of the rubber band 1, and this engagement wall 2 is brought into contact with the side edge of a tank bracket 4 that has been previously attached to the engine body. In particular, the positioning when installing the fuel tank 3 is performed.

However, since the engagement wall 2 is a part of the rubber band 1 erected, its rigidity is low, and therefore it is easily bent due to impact, and has the disadvantage that it requires little response when positioning. It was hot. For this reason, it is conceivable to make the engagement wall 2 thicker, but
This poses a problem in that the elasticity of the rubber band 1 itself decreases, making it difficult to attach it to the outer periphery of the fuel tank 3. Also, the tank bracket 4 of this engagement wall 2
Since the contact surface with the fuel tank 3 serves as a reference surface when attaching the fuel tank 3, there is a problem in that the fuel tank 3 wobbles against the tank bracket 4 if the contact surface is not formed accurately.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a fuel tank mounting device that is easy to mold and can accurately perform the function of positioning the fuel tank.

In order to achieve the above object, the present invention includes attaching a tank bracket to the engine body, placing a fuel tank on the tank bracket with a cushion material interposed therebetween, and tightening a band that locks the fuel tank to the tank bracket. In the fuel tank mounting device which is fixed to the tank bracket by means of a fuel tank, a projection for engaging a cushion material is provided on the outer periphery of the fuel tank, and a projection for engaging the cushion material is provided on the cushion material. A hole is formed in the cushion material, and a protrusion for engaging a tank bracket is provided protruding from the cushion material, and the tank bracket has an engagement hole into which the protrusion for engaging the tank bracket of the cushion material engages, and the cushion material of the fuel tank. After the engagement protrusion passes through the engagement hole of the cushion material, an engagement hole is formed into which the tip end thereof is engaged.
