Abstract: A key interlock mechanism for a column automatic-transmission operating device includes a key lock lever having one end with a slot and swingably supporting the lock pin through the slot, a shank formed with the key lock lever, a guide groove formed with a unit base and cooperating with the shank to rotatably support the key lock lever so as to bias a lock pin in the direction of protruding into a key cylinder, and a key lock lever spring wound around the shank for biasing the key lock lever so that the lock pin protrudes into the key cylinder and for returning to a given position another end of the key lock lever which has moved along the guide groove.

Abstract: A mechanism is provided for controlling vehicle ignition lock and transmission shift lock in an interlocked relation to each other. The mechanism comprises a lock member movable into a lock position for blocking up a passage to a Park position of a position plate. An operating member drives the lock member into the lock position in response to upward movement of a position pin in the Park position. A stopper of an ignition lock is movable between a lock position for preventing rotation of a key rotor into a lock position and an unlock position for allowing the same. A cable interconnects the lock member and the stopper to allow them to move in unison such that movement of the lock member into the lock position causes the stopper to move into the unlock position and movement of the stopper into the lock position causes the lock member to move into the unlock position. A spring is installed in the ignition lock for urging the stopper toward the lock position.

Abstract: In an automatic transmission shift control device, a rocking lever and a second biasing unit are provided for holding a selector lever in a shiftable condition when the selector lever is in one of the gear positions other than a parking position. A first biasing unit is provided for holding the selector lever in a locked condition when the selector lever is in the parking position. A solenoid is provided for releasing the selector lever from a locked condition when energized. The solenoid is energized only when a brake pedal is fully depressed under a condition where an ignition key is in an "ON" position and the selector lever is in the park position.
