PROBLEM TO BE SOLVED: To control the resonance frequency of rigid body resonance based on axial vibration.SOLUTION: A large ball part 13 of a torque rod 10 is constituted by an outside frame part 20, an inside member 21, an intermediate ring 22 and an elastic vibration prevention main body 23. The outside frame part 20 and the intermediate ring 22 are integrally connected to the elastic vibration prevention main body 23, an inside gap 36 surrounding the periphery of the inside member 21 is provided between the intermediate ring 22 and the inside member 21, and the intermediate ring 22 is freely movable in an axial direction with respect to the inside member 21. Regarding vibration in a fitting shaft direction, a spring in the fitting shaft direction (a C3 direction) becomes weaken by integrally moving the outside frame part 20, the intermediate ring 22 and the elastic vibration prevention main body 23 in the axial direction with respect to the inside member 21, and then the resonance frequency of rigid resonance in the fitting shaft direction decreases. |
