Vibration damping device

摘要

A vibration damping device capable of achieving sufficient vibration damping effect utilizing members for converting kinetic energy into thermal energy. In the vibration damping device, a plurality of members is attached to an object to be vibrated in a manner to displace relatively while being contacted with each other, and vibrations of the vibrating object is damped by converting kinetic energy resulting from the vibrations of the object into thermal energy by the relative displacement of the plurality of members. The vibration damping device includes a tightening member, which is attached to the plurality of members to tighten the plurality of members so as to increase frictional force among the plurality of members.

1. A vibration damping device for damping vibrations of a transmission case mounted on a vehicle, comprising:
strands prepared by twisting a plurality of wires; a clasp member having a cylindrical connecting member that tightens one end of the strands inserted thereto; a terminal portion integrated with the clasp member; a boss portion formed to protrude from the transmission case to which the terminal portion is fixed; a covering member that covers and tightens the strands; and a tightening member that tightens the strands from outside through the covering member at a free end side of the strands.
