Claims

[Claims for Utility Model Registration] A vibration isolator comprising an inner member, an outer member, and an elastic support body that connects the inner member and the outer member in the radial direction, A vibration isolator characterized in that a vibration transmission path leading to the inner member is provided with a protrusion that resonates in a frequency range in which the supporting elastic body causes bending resonance.
