Abstract:
A large ring part of a torque rod includes an outer frame section, an inner member, an intermediate ring and an elastic vibration isolating main body. The outer frame section and the intermediate ring are integrally combined with the elastic vibration isolating main body. An inner clearance is provided between the intermediate ring and the inner member such as to surround the circumference of the inner member. The intermediate ring is movable relative to the inner member in the axial direction. With respect to the vibration in the direction of a mounting shaft, the outer frame section, the intermediate ring and the elastic vibration isolating main body move together in the axial direction in relation to the inner member, whereby the spring in the direction of the mounting shaft is weakened and the resonance frequency of the rigid body resonance in the direction of the mounting shaft is decreased.
