PURPOSE:To absorb the three order vibration by contacting a portion having a rotary ball and another portion having a recessed face through a ball while providing the recovery force on both portions through a spring. CONSTITUTION:It is combined such that a ball 2 in a component A and a parabolically recessed face 1 in the component B will contact where the expansion/ shrinking having the recovery force in X, Y direction is provided by the force of the ball 2 to return to the center of said face 1 thus to enable the expansion/ shrinking of the component A in Z direction. While a sliding mechanism 14 comprising a piston 8, cylinder, etc. reciprocate through a spring 13 is provided to achieve the recovery force in the three order direction. |
