Title:
VIBRATION-PROOF DEVICE
Document Type and Number:
Japanese Patent JP2016065576
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable approximately all vibrations to be attenuated and absorbed and an attenuation effect to be improved by arranging many resonant oscillations in one set.SOLUTION: This invention provides a vibration-proof device 1A comprising an upper fixing member 2 fixed to a vibration generating part 11; a lower fixing member 3 fixed to a vibration receiving part 12; a resilient body 4 composed of rubber material and the like connecting the upper fixing member 2 and the lower fixing member 3; a cylindrical body 5 arranged at the resilient body 4 and having a higher rigidity than that of the resilient body 4; and attenuation material arranged in at least one portion of the resilient body 4 and exerting an attenuation effect, and a part of the resilient body 4 is fixed over an entire region of an inner peripheral surface 5a of a cylinder body 5.SELECTED DRAWING: Figure 2
