PURPOSE:To absorb primary and secondary vibrations by applying a three- dimensionsl suspension. CONSTITUTION:A constitutional part A having a rotating ball 2 and constitutional part B having a spherically concaved surface 1 can perform extensible and contractible action with force of restoring to directions X, Y by force, in which the ball 2 tends to return to the center of the spherically concaved surface, in accordance with combination of a contact between the ball 2 and the surface 1, then a slide mechanism consisting of a piston 8 and cylinder 9 restored by a spring 13 enabling the action of telescopic motion to a direction Z is provided to said part A to constitute a supportring mechanism which enables the action as a whole of extension and contraction with restoring force to the three-dimensional directions. A suitable wheel is assembled to a three-dimensional suspension of this constitution. |
