  • Vibration damping device
    Patent number: 9051733
    Abstract: A vibration damping device for suppressing vibrations of a structure includes: a slide body mechanism having a concave slide body and a convex slide body which are fixed to the structure and are arranged so as to be slidable relative to each other in a reciprocating manner; and a biasing means which pushes the slide bodies to each other. Each slide body has: a first slide surface having a shape which increases a height of the slide body mechanism 2 along with the increase of a displacement amount of the slide body in one sliding direction from a neutral position relative to the counterpart slide body; and a second slide surface having a shape by which the height of the slide body mechanism is increased along with the increase of the displacement of the slide body in the other sliding direction from the neutral position.
