Abstract
A motion snubbing device in which an internal gear is fixed on a shaft rotating in accordance with relative axial movement of a pair of support members, and an inertia mass is rotated by operation of a planetary gearing mechanism with the internal gear as an input gear thereof on its own axis. When the level of drastic external force applied to the device exceeds a critical value, the planetary gearing mechanism starts revolving induced by retarded rotation of the inertia mass. An actuating lever connected to the planetary gearing mechanism applies initial force for constrictive winding to a clutch spring which is normally at a standstill, thereby causing the spring to wind automatically around a brake drum fixed on the shaft so that the shaft is prevented from rotation through the drum.
