Abstract

The present invention provides a vibration isolation structure of a fuel tank for a vehicle, it is possible to reconcile a retaining load on and the vibration isolation function of the cushion rubber member interposed between the fuel tank and the vehicle body. In a vibration isolation structure of a fuel tank for a vehicle, first projections 30, second projections 31 and third projections 32 having different projecting heights are formed on a surface of a vibration-isolation cushion rubber member 23 interposed between a tank body 11 and a floor panel 24, the surface contacting the floor panel 24. When the tank body 11 is pushed against the floor panel 24, the amounts of compression of the projections 30, 31 and 32 are changed in accordance with the heights of the projections 30, 31 and 32, thereby ensuring a vibration isolation function of preventing noise and vibration of the tank body 11 from being transmitted to a vehicle body, while ensuring a function of retaining the tank body 11 on the floor panel 24.

Description

technical field [0001] The invention relates to an anti-vibration support structure of a fuel tank for a vehicle, wherein a buffer rubber pad is sandwiched between the tank body and the vehicle body. Background technique [0002] When the fuel tank of an automobile is mounted on the vehicle body with bolts or metal straps, a buffer rubber pad is sandwiched between the surface of the tank body and the contact portion of the vehicle body, so that the noise and noise generated by the fluctuation of the fuel in the tank body Vibration is difficult to transmit on the car body, and such technology has been disclosed by Japanese Patent Application Laid-Open Publication No. 6-106999 and Japanese Patent Application Publication No. 5-89060. [0003] However, the buffer rubber pad in the above-mentioned prior art is composed of a plate-shaped rubber pad with a certain thickness, so it is difficult to fully exert the anti-vibration function. Therefore, it is also known to improve the a...
