PURPOSE:To adjust the movement shift of a mass body supported by a bush with high precision by changing the spring characteristic of the load applied on a bush according to the directions of the inputs in two directions. CONSTITUTION:An elastic member 2 is fixed on an inner cylinder 3 or outer cylinder 4, and on one end side in the axis line direction, the first rubber bush 1a is fixed on the side where the elastic member 2 between the inner cylinder 3 or outer cylinder 4, is not fixed and on the other end in the axis line direction, the second rubber bush 1b is fixed on the cylinder on which the elastic member 2 is not fixed. The modulus of the first rubber bush 1a is set smaller in the axis line direction than the modulus of the second rubber bush 1b. |
