Abstract
A vibration-damping device for damping vibrations of a vibrative member of a vehicle, including: a mass member disposed in the vibrative member such that the mass member is non-adhesive to and is displaceable independent of and relative to the vibrative member; the mass member and the vibrative member being brought into impact against with each other at their abutting portions. At least one of the abutting portions of the mass member and the vibrative member is formed of an elastic member adapted to undergo shear deformation in a direction in which the mass member and vibrative member are brought into impact against each other.
Claims15
A vibration-damping device for damping vibrations of a vibrative member of a vehicle, comprising:
- a rigid housing having a hollow structure and being fixable to the vibrative member, said housing defining a hollow space therein;
- and
- a mass member being accommodated within said hollow space with a spacing therebetween such that said mass member is non-adhesive to and is displaceable independent of and relative to said housing,
- said housing partially defined by an elastic member to provide an abutting portion of said housing on which an abutting portion of said mass member is brought into impact,
- at least one of said abutting portions of said mass member and said housing being formed of an elastic member adapted to undergo shear deformation due to a load applied thereto in a direction in which said mass member and said housing are brought into impact against each other.
