BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank supporting device for an engine, and more particularly, to a device capable of preventing fuel scattered from a fuel tank from adhering to a vibration isolating rubber and stopping a vibration isolating support. .

[0002]

2. Description of the Related Art FIG. 4 shows a prior art of a fuel tank supporting device for an engine. It has the same basic structure as the present invention. That is, the end plates 107 are fixed to both ends of the anti-vibration rubber 106, and the bracket 101 fixed to the engine body E is used by using the anti-vibration support 105 which is configured by erecting the screw rod 108 on each end plate 107. One of the screw rods 108 is penetrated and fastened by a nut 119, and the other screw rod 108 is passed through a mounting plate 103 provided on the fuel tank 102 and fastened by a nut 119.

[0003] By the way, in this prior art, the vibration isolating rubber 1 is used.
Reference numeral 06 denotes an exposed state, and the anti-vibration support 105 is not stopped.

[0004]

The above prior art has the following problems. Due to the vibration of the fuel tank 102, the fuel inside scatters around from the air vent hole of the cap 104 attached to the fuel supply port to the surroundings.
6 and may be degraded. For this reason, this is a factor that shortens the useful life of the anti-vibration rubber 106.

If the nut 119 is to be fastened to the threaded rod 108 when the fuel tank 102 is mounted on the engine body E, the anti-vibration support 105 is dislodged, and it is difficult to fasten the nut.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fuel tank supporting device for an engine which can prevent fuel scattered from a fuel tank from adhering to a vibration isolating rubber and can prevent a vibration isolating support from rotating. is there.

[0007]

According to the present invention, as shown in FIG. 1, end plates 7, 7 are fixed to both ends of an anti-vibration rubber 6, and a screw rod 8 is erected on each end plate 7. One of the screw rods 8 penetrates through the bracket 1 fixed to the engine body E and is fastened with a nut 19 using the vibration damping support 5 thus configured, and the other screw rod 8 is mounted on the mounting plate 3 provided on the fuel tank 2. A fuel tank support device for an engine, which is penetrated and fastened with a nut 19, is characterized as follows.

That is, the vibration-proof rubber 6 is covered with an oil-proof body 12, one end plate 7 is fitted into the oil-proof body 12, and the oil-proof body 12 is prevented from rotating. Characterized by being fixed or locked to at least one of them.

[0009]

Operation and effects of the present invention As shown in FIG. 1, the present invention has the following operations and effects. Even if the fuel inside the fuel tank 2 scatters from the air vent hole of the cap 4 attached to the fuel supply port to the surrounding due to the shaking of the fuel tank 2, the vibration isolating rubber 6
Adhesion to the oil is prevented by the oilproof body 12. For this reason,
The deterioration of the vibration isolating rubber 6 due to the adhesion of the fuel is prevented, and the service life thereof can be extended.

[0010] The whole of the anti-vibration support 5 is composed of the end plate 7 and the oil-proof body 12.
When the fuel tank 2 is mounted on the engine body E, the anti-vibration support 5 does not rotate and the nut is easily fastened to the threaded rod 8 when the fuel tank 2 is mounted on the engine body E. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
1 and 2 are diagrams for explaining the first embodiment. As shown in FIG. 1, the engine used in this embodiment is a vertical overhead valve engine, and its configuration is as follows. That is, as shown in FIG. 1A, the vertical bracket 1 is fixed to the cylinder head 13 of the engine body E, and the fuel tank 2 is supported by this. The upper end of the bracket 1 is bent into a hook shape to form a horizontal receiving seat 15a, and the lower end is bent up to form a vertical receiving seat 15b. The fuel tank 2 is provided with a mounting plate 3 whose upper portion is bent into an L-shape to form a horizontal mounting seat 16a and a lower portion is formed as a vertical mounting seat 16b. Fuel tank 2
A cap 4 having an air vent hole is fitted to a fuel supply port provided at an upper portion of the fuel cell.

[0012] A protection is provided between the horizontal receiving seat 15a of the bracket 1 and the horizontal mounting seat 16a of the mounting plate 3, and between the vertical receiving seat 15b of the bracket 1 and the horizontal mounting seat 16b of the mounting plate 3, respectively. A vibration support 5 is interposed.

[0013] As shown in FIG.
Is to fix the end plates 7.7 to both ends of the columnar vibration isolating rubber 6,
A screw rod 8 is provided upright on each end plate 7. The upper screw rod 8 penetrates the lateral mounting seat 16a, the lower screw rod 8 penetrates the horizontal receiving seat 15a, and the nut 19 is fastened to each screw rod 8. In addition, the vertical receiving seat 15b and the vertical mounting 16
The anti-vibration support 5 between b is mounted in the same manner.

In this embodiment, in order to prevent the fuel scattered from the fuel tank 2 from adhering to the anti-vibration rubber 6 and to prevent the anti-vibration support member 5 from rotating, the following will be described. A configuration is employed. That is, as shown in FIG. 1B, the vibration-proof rubber 6 is covered with the oil-proof body 12 together with the one end plate 7. As shown in FIG. 2, the oil preventive body 12 is a cylindrical cap with a bottom, and its peripheral wall has a flat surface 1.
7 and 17 are provided to face each other. The end plate 7 is substantially disk-shaped, and a notch edge 11 is formed in a straight line parallel to a peripheral edge thereof. Then, one end plate 7 is fitted inside the oil preventive body 12, and the linear cutout edge 11 of the end plate 7 is brought into contact with the flat surface 17 of the oil preventive body 12, and the end plate 7 is connected to the oil preventive body 12. Has been stopped. Further, as shown in FIG. 1B, the end face 10 of each end plate 7 is connected to the end plate 18 of the oilproof body 12, the receiving seats 15a and 16
a.

The end wall 18 of the oil preventive body 12 is fixed to the mounting seat 16a of the mounting plate 3 by spot welding, whereby the oil preventive body 12 is prevented from rotating around the mounting seat 16a. This detent may be performed by locking the detent piece 22 derived from the oilproof body 12 to the seat 15a as shown by a chain line. In addition, the end circle 22 of the oilproof body 12
A non-interference space 23 is held in front of “a” so that even when the anti-vibration rubber 6 is maximally contracted, the end circle 22 a of the oil-proof body 12 does not interfere with other parts.

According to such a configuration, even if the fuel inside scatters around from the air vent hole of the cap 4 attached to the fuel supply port due to the shaking of the fuel tank 2, the fuel is not applied to the vibration isolating rubber 6. The adhesion is prevented by the oilproof body 12. Also,
Since the whole of the anti-vibration support 5 is stopped by the bracket 1 or the mounting plate 3 via the end plate 7 and the oil-proof body 12, when the fuel tank 2 is mounted on the engine body E, the anti-vibration support 5 is displaced. There is no rotation, and the work of fastening the nut to the threaded rod 8 becomes easy.

Next, a second embodiment of the present invention will be described. FIG. 3 is a diagram for explaining the second embodiment. In the second embodiment, the bottomed cylindrical cap-shaped oil preventive body 12 of the first embodiment is changed to a cylindrical shape having no bottom. Other structures are the same as those of the first embodiment, and the same elements are denoted by the same reference numerals.
