Title:
VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019027510
Kind Code:
A
Abstract:
To secure smooth circulation for fluid from a second liquid chamber side to a first liquid chamber, and also adjust developing attenuation force and dynamic spring constant.SOLUTION: A first attachment member 11 comprises: an elastic membrane 32 for closing an open hole 23 opened to a first liquid chamber 26; switching means 37 capable of switching between a suppression state of operating an outer surface of the elastic membrane 32 to suppress deformation of the elastic membrane 32 toward the outside of the first liquid chamber 26, and an allowance state of releasing the outer surface of the elastic membrane 32 to allow deformation of the elastic membrane 32 toward the outside of the first liquid chamber 26; and a suppression part 23c opposite to at least a center part of an inner surface of the elastic membrane 32, and suppressing deformation of the elastic membrane 32 toward the inside of the first liquid chamber 26.SELECTED DRAWING: Figure 1
