Abstract

A shock-absorbing joint includes a tubular casing connected securely to the front wheel-carrying frame member of a bicycle, and confining an accommodating space with a central axis that is disposed horizontally and that extends in a transverse direction relative to a riding direction of the bicycle. A coupling shaft is disposed in the accommodating space, and extends along the central axis of the accommodating space. A spiral spring plate is disposed in the accommodating space, and has an innermost end connected to the coupling shaft and an outermost end connected to the tubular casing. The spiral spring plate is wound about the coupling shaft to form a series of interconnected turns of increasing radius. A connecting bracket is connected securely to a rear wheel-carrying frame member of the bicycle. The tubular casing is mounted rotatably on the connecting bracket, while the coupling shaft is mounted non-rotatably on the connecting bracket.
