Classification: CPC F  G | IPC F

Claim 8:
9. A vibration-proof hanger, comprising:
a fitting bracket having a fixed plate configured to allow a first surface thereof to be integrally fixed to an artificial structure, wherein a hinge unit is provided on a second surface of the fixed plate;
a tilting arm unit configured to allow a first end thereof to be rotatably fixed to the hinge unit to be tilted; and
a vibration-proof unit configured to be coupled to the tilting arm unit to absorb vibration transferred to the tilting arm unit or rotate to prevent the vibration of the tilting arm unit,
wherein the vibration-proof unit comprises at least one of an absorption-type vibration-proof module coupled to a central portion in a longitudinal direction of the tilting arm unit to absorb the vibration of the tilting arm unit and a rotation-type vibration-proof module coupled to the tilting arm unit and provided rotatably,
wherein the rotation-type vibration-proof module is provided in a dual manner to face both sides with respect to the tilting arm unit, and each of the rotation-type vibration-proof modules comprises:
a first vibration-proof ball joint coupled to one end of a fixed plate side of any one selected from an upper arm and a lower arm, and including a first ball joint penetrating portion;
a vibration-proof rod having one end connected to the first vibration-proof ball joint and disposed to cross longitudinal directions of the upper arm and the lower arm; and
a second vibration-proof ball joint connected to the other end of the vibration-proof rod, and including a second ball joint penetrating portion.
