Title:
VIBRATION ISOLATION DEVICE
Document Type and Number:
Japanese Patent JP2017145863
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration isolation device in which an orientation of vibration whose transmittance is restricted is not limited to one direction, but vibrations in two directions that are different from each other can be restricted.SOLUTION: A first spiral spring 24 is a non-contact type spiral spring. In addition, a rod member 20 has a first inner abutting part 203. The first inner abutting part 203 abuts against the first spiral spring 24 from inside at a spring radial direction DRr. Further, a first outer abutting part 222 of a first holder 221 abuts against the first spiral spring 24 from outside of the first spiral spring 24 at the spring radial direction DRr. Along with this operation, a first axial abutting part 223 of the first holder 221 abuts against the first spiral spring 24 at a position shifted to the spring radial direction DRr in respect to a location 242 to which a first prescribed abutting part 26 abuts in the first spiral spring 24. Accordingly, a vibration isolation device 10 enables a transmittance of vibrations in two directions that are different from each other at a rod member axial direction DRa and the spring radial direction DRr to be restricted.SELECTED DRAWING: Figure 1
