ABSTRACT:
A shift lock arrangement for an automatic transmission shift lever device having a shift lock lever in contact with a position pin of the shift lever device positioned in a parking position has a lock lever in contact with the shift lock lever to restrict the movement of the position pin in the parking position. A key lock unit is connected with the shift lock lever so that the shift lock lever keeps latching the position pin in the parking position when an automotive key is not set therein. A slidable stopper pin is connected with a push rod pushed by a brake pedal in a released condition. The stopper pin latches the shift lock lever so as to prevent the movement of the position pin from the parking position to the other positions when the brake pedal is in the released condition. When the brake pedal is depressed, the push rod is released from the brake pedal and the stopper pin is disengaged from the shift lock lever. Therefore, the shift lever device is locked in the parking position when the key is not set in the key lock unit or when the brake pedal is not depressed.
