Abstract
The device for coupling a shaft provided with a rod (10) having a noncircular end (11) and a shaft provided with a yoke (20) having a U-shaped fork (21) capable of pivoting in a direction (25) perpendicular to their common axis (X--X) comprises a guide surface (321) on the yoke, a sleeve (330) at least partially enclosing the yoke and movable relative to the latter so as to unmask or mask the U of the fork, a resilient coil spring (340) normally biasing the sleeve to mask the fork, and a locking bolt (350) retaining the sleeve against the resilient bias. Application to motor vehicle steering systems when the rod is fastened to a pinion and the yoke is fastened to a universal joint jaw.
