  • Tank rubber cushion
    Patent number: 8857800
    Abstract: A tank rubber cushion for providing a vibration-damping support of a fuel tank against a vehicle body, including two divided rubber cylinders inserted onto an inner axial member having flanges at both axial ends and to be inserted through a mounting hole formed in a support portion of the fuel tank. Each of the divided rubber cylinders is provided with an axial vibration-damping rubber portion arranged between opposing surfaces of the flange of the inner axial member and the support portion in an axial direction, and a transaxial vibration-damping rubber portion arranged between opposing surfaces of the inner axial member and the support portion in a transaxial direction. The transaxial vibration-damping rubber portion includes a concave/convex portion wherein a diameter varies in a circumferential direction so that an assembly can be made with a gap between the inner axial member and the support portion.
