Title:
VIBRATION ISOLATOR
Document Type and Number:
Japanese Patent JP2023161998
Kind Code:
A
Abstract:
To provide a vibration isolator which can be sufficiently changed in stiffness by a simple constitution while using a magnetic fluid.SOLUTION: A vibration isolator 100 of the present invention includes an inside attachment member 1, a cylindrical outside attachment member 2, an elastic body 3 arranged between the inside attachment member 1 and the outside attachment member 2, and a liquid chamber 4 using the elastic body 3 as at least a part of a chamber wall. In the vibration isolator 100, a portion 23 protruding toward the liquid chamber 4 in a radial direction is formed at the outside attachment member 2, a magnetic fluid MF is sealed into the liquid chamber 4, and at least a part of the protrusion 23 of the outside attachment member 2 in a circumferential direction is constituted of at least a part of electromagnets 24 including a yoke 241 and an electromagnetic coil 242 which is wound around the yoke 241. The electromagnets 24 are arranged in a plurality of pieces in the circumferential direction.SELECTED DRAWING: Figure 1
