Abstract: An improved ignition rack and an improved sector gear for a steering column in a vehicle inhibits theft of the vehicle. The ignition rack is used to operate an electrical switch mounted in the vehicle. The vehicle has a key receiving assembly rotatably mounted in the steering column and a shaft with a first end joined to the key receiving assembly for rotation therewith. A second end of the shaft is joined to the sector gear, the sector gear having teeth located on a portion of an outer perimeter. In a first embodiment, the ignition rack includes a guard flange for inhibiting removal of the sector gear from the shaft. The sector gear also includes a guard flange that forms a recess which opens to a surface opposite the guard flange of the ignition rack. The sector gear with the guard flange formed thereon protect a spring connected to the sector gear and a locking bolt from attack.
