PROBLEM TO BE SOLVED: To improve a transmission suppression effect of vibration produced by an elastic member at the initial stage at which a load acts on the elastic member and when a small load acts thereon, to improve the isotropy of the vibration isolation performance of the elastic member, thereby improving the vibration isolation performance of the elastic member, in a vibration isolation support device having the elastic member which is arranged between a vehicle body and a fuel tank.SOLUTION: The vibration isolation support device includes the elastic member 20 which is arranged between the vehicle body 2 and the fuel tank 10, and the transmission of vibration between the vehicle body 2 and the fuel tank 10 is suppressed through the elastic deformation of the elastic member 20. The elastic member 20 is an annular body formed by connecting a plurality of spherical bodies 30 which are arranged in an annular shape with an axial line parallel to the vertical direction as a center, and has a plurality of spherical parts 31, 32 which are arranged in an annular shape. The plurality of spherical parts 31, 32 have substantially the same shapes, and contact with the vehicle body 2 and the fuel tank 10 respectively in the vertical direction. |
