PURPOSE:To reduce the vibration transmitting characteristic considerably, by forming such that the vibrating directions of suspension member and sub-member will be in counter phase. CONSTITUTION:A sub-member 20 of elongated plate is arranged in front of a rear suspension member 1 to rigid joint the central portion of sub-member 20 to the rear suspension member 1 through a sub-member bracket 21. Both sides of the sub-member 20 are projected outwardly in lateral direction similarly with the rear suspension member 1 while sub-member side tubular rubber bushes 22 are fixed to the opposite ends. Consequently, bending resonance and vibration characteristic of rear suspension member 1 and sub-member 20 are utilized to cancell the bending resonance of rear suspension member 1 with the vibration of sub-member 20, thus to reduce the force transmission characteristic of rear suspension member 1 in the resonant frequency region. |
