Abstract
A device for effecting fine adjustment of the orientation of a steering wheel on a shaft (10), which are joined together by a fastener (30), has a sleeve (40) interposed between the end (11) of the shaft (10) and the hub (20) of the steering wheel. The sleeve and the shaft define between them an annular chamber (42) in which is housed a friction member (50) opposing their spontaneous relative rotation. The fine adjustment, limited to a value of about 9.degree., is made with the aid of an arrangement including a control mechanism, amplitude limiters, and stops. These stops ensure continuity of transmission of the torque exerted on the steering wheel to the shaft in the event of slackening of the fastener or failure of the amplitude limiters.
