ABSTRACT:
A holding device and a transmission shift interlock mechanism employing the holding device. The holding device is intended to immobilize a cable and includes a generally cylindrical electromagnet with a central passageway extending therethrough and a holding assembly comprised of a ferromagnetic body joined to a tubular non-magnetic stem. The ferromagnetic body and stem have a passageway therethrough and the stem passes through the central passageway of the electromagnet. The cable passes slidably through the stem and a stop collar is secured to the cable immediately forwardly of the stem for abutting coaction with the forward end of the stem. In the transmission shift interlock mechanism, the cable extends from an ignition switch interlock member to a park/lock member pivotally mounted beneath the steering column of the vehicle and acting in the locked position thereof to preclude movement of the shift lever detent from the park detent position to a drive or reverse detent position of the vehicle automatic transmission. The holding device is piggy-backed on the cable proximate the park/lock lever and includes a mounting bracket securing the holding device proximate the park/lock member.
