Abstract: In an automobile steering device, a mounting structure is provided for attaching a locking collar having a cancel cam to the hub of a cable reel rotor. The cancel cam is used to automatically deactivate a turn signal switch while it is blinking. The cable reel provides a housing for cable. The cable reel includes a casing attached to a rotor having an inner hub. In an annular hollow area between the casing and the rotor, a flat cable is spirally housed, and the flat cable is wound or rewound in the hollow area in accordance with reciprocal rotation of the rotor which corresponds to steering wheel movement. During the assembly process (i.e. attachment of locking collar to the rotor), it is important that the cancel cam is aligned, or clocked, to a specific radial position with respect to the rotor. There is provided a mounting structure which positively prevents erroneous connections between the locking collar and rotor.
