Title:
VIBRATION PREVENTION DEVICE
Document Type and Number:
Japanese Patent JP2019113177
Kind Code:
A
Abstract:
To provide a vibration prevention device of a novel structure capable of reducing deformation rigidity required for a cylindrical outer member that is mounted to a second mount member in a dynamic damper, and improving deformation rigidity of the cylindrical outer member without being thickened.SOLUTION: In a vibration prevention device 10 having a structure in which a first mount member 18 and a second mount member 20 ate elastically coupled with each other by a main body rubber elastic body 22, a bracket 14 is mounted to the second mount member 20, and the bracket 14 includes a mounting part 52 that is mounted to any one of members constituting a vibration transmission system. On the other hand, a cylindrical outer member 60 that is press-fitted and fixed into the second mount member 20 is provided, a mass member 58 is disposed in an inner periphery of the cylindrical outer member 60, and the cylindrical outer member 60 and the mass member 58 are elastically coupled by a support rubber 62 which is fixed in an outer peripheral portion of the mass member 58, thereby configuring a dynamic damper 16.SELECTED DRAWING: Figure 1
