A hole is formed in a damper rubber, where by when a compressive load is small, pillar portions undergo a flexural deformation so as to result in buckling deformation. On the other hand, when the compressive load becomes large, the hole collapses and the damper rubber under goes a compressive deformation so as to collapse itself. Thus, since the damper rubber has a non-linear characteristic such that an elastic modulus thereof at an amount of deformation exceeding a predetermined amount is larger than that at an amount of deformation less than the predetermined amount, the transmission of a large torque can be implemented while absorbing a torque fluctuation sufficiently.
