VIBRATION PROOF MOUNT

PROBLEM TO BE SOLVED: To protect a rod shaped member against damage due to vibration, the rod shaped member restricting the interval of the upper and the lower mounts which constitute the vibration proof mount.SOLUTION: The vibration proof unit 30, which is provided between the upper mount 2 and the lower mount 3, consists of an upper vibration absorbing rubber 32U, a lower vibration absorbing rubber 32B and the partition plate 33M which is arranged between them. The upper and lower regulation plates 41U, 41B, which constitute the mount interval restriction unit 40, are attached to the upper mount 2 and the lower mount 3, and the bolt 42 is fixed to the regulation plate 41B and extended upwards penetrating the through hole 43 which is bored in the regulation plate 41U. The stopper plate 44 and the over load prevention plate 45 are provided to the bolt 42, and the stopper plate 44 is contacted with the regulation plate 41U if the lower mount 3 becomes free, and separated from the regulation plate 41U if the load acts on the vibration proof unit 34. The protection sleeve 46 is fitted to the bolt 42 so as to be sandwiched between the stopper plate 44 and the over load prevention plate 45.
