Title:
VIBRATION DAMPING APPARATUS
Document Type and Number:
Japanese Patent JP2005009565
Kind Code:
A
Abstract:

To provide a vibration damping apparatus which has been improved so as to effectively damp even the vibration causing a high speed and a large amplitude.

The vibration damping apparatus comprises a rotary shaft driving mechanism 10 for turning a rotary shaft 12 by the relative displacement produced between a first structural member 1 and a second structural member 2, and a brake mechanism 50 for generating frictional resistance by pushing brake shoes rotating together with the rotary shaft 12 against a slide surface by the centrifugal force applied to the brake shoes. Even if the speed of the relative displacement produced between the first structural member 1 and the second structural member 2 becomes high, the vibration can be damped by surely generating the frictional resistance. Further, because the length of a rack composing the rotary shaft driving mechanism 10 can be set so as to have an arbitrary length, the vibration can be damped by surely generating the frictional resistance even if the amplitude of the relative displacement becomes very long.
