VIBRATION STOPPER STRUCTURE OF VIBRATION CONTROLLER

PURPOSE: To reduce the dimension of a vibration controller and improve the vibration controllability by preventing the sharp variation of the spring constant. CONSTITUTION: A vibration stopper structure is equipped with the first supporting body 2 having a peripheral wall 6 around the vibration center line C, elastic body 4 connected with the inner peripheral surface of the peripheral wall 6 of the first supporting body 2, and the second supporting body 3 which is connected with the elastic body 4 so as to relatively shift in the vibration center line C direction for the first supporting body 3, and one between the first and the second supporting bodies 2 and 3 is fixed with the vibration input side and the other is fixed with the vibration transmission side. Between the first and the second supporting bodies 2 and 3, a stopper 12 is extended toward the vibration center line C of both the supporting bodies 2 and 3 from the connection end part of the peripheral wall 6 of the first supporting body 2 for the elastic body 4, and the gap S of the interval 15 formed between the stopper 12 and the elastic body 4 becomes larger toward the vibration center line C from the connection end part of the peripheral wall 6. When the first and the second supporting bodies 2 and 3 shift relatively, the elastic body 4 gradually makes contact with the stopper 12.
