Title:
VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019060454
Kind Code:
A
Abstract:
To provide a vibration control device with a novel structure which can prevent deterioration of a body rubber elastic body, and can stably generate elastic deformation of the body rubber elastic body.SOLUTION: In a vibration control device 10, a first attachment member 12 and a second attachment member 14 are connected with each other by a body rubber elastic body 16. An outer surface 19 of the body rubber elastic body 16 is covered by a flexibly deformable protective film 24 having air shutoff properties, and thereby, a closed space 40 blocked from the atmosphere is formed between the body rubber elastic body 16 and the protective film 24. The closed space 40 is kept in negative pressure more than the atmosphere, and the protective film 24 is located adjacent to the outer surface 19 of the body rubber elastic body 16, and a region 48 is provided in which the protective film 24 is separated from the body rubber elastic body 16.SELECTED DRAWING: Figure 1
