Claims

[Scope of utility model registration request]

The inner cylinder is equipped with an inner circumference, an outer cylinder surrounding the inner cylinder, and an elastic body loaded between the inner and outer cylinders, and the inner cylinder is attached to either a fixed member or a vibrating member, and the outer cylinder In the vibration isolator, one end of the outer periphery of the outer cylinder is attached to the other of the fixed member or the vibrating member, thereby supporting the vibrating member on the fixed member side with a vibration damping function. A vibration isolator characterized in that a mass body or a reinforcing portion is provided at an end portion on the opposite side.
