ABSTRACT:
In a steering shaft locking and unlocking arrangement including a key-operated cylinder lock unit, the rotor of which is mechanically coupled with a cam for control of a spring-biased locking and unlocking bolt, a checker is fixedly mounted on the rotor. A combined hook-and-lever unit is provided for cooperation with the checker, so as to prevent unintentional steering shaft locking while the vehicle is running. For this purpose, the combined unit is mechanically coupled with a vehicle speed control lever through cable means, so as to prevent the cylinder lock rotor from turning to the locking position.
