<p>A lockable castor for supporting a movable body, for example, a refuse container, comprises an element (2) for fixing to the movable body, and a fork (3) which supports a rotary wheel (7) and is articulated to the fixing element on a steering axis (A). A resilient brake plate (34) is force-fitted between two facing surfaces belonging, respectively, to a bracket (32) and to an appendage (33) formed by the partial blanking of the bracket. A central, axially-movable operating pin (26) cooperates with the resilient plate (34) to stop the rotation of the wheel (7) and simultaneously cooperates with a toothed disc (29) which engages stops formed in the cheeks (4) of the fork (3) by partial blanking. The fixing element (2) comprises a central polygonal hole (15), an axial shank (20) having a cross-section with a polygonal profile and a peripheral end tooth for the coupling and snap fitting with the central hole (15). <IMAGE></p> |
