ABSTRACT:
The car locking device of the present invention has a latch to be engaged with a striker, a ratchet for preventing the reversal of said latch, an opening lever for disengaging said ratchet from said latch, a locking lever for changing over said intermediate lever and said opening lever between an engaged state (unlocked state) or a disengaged state (locked state), and the first and second change-over levers. The key device of a door is connected to said first change-over lever, and said locking lever is connected to said second change-over lever. Said first and second change-over levers are rotationally moved together by key operation between the locking position and the unlocking position, and in the case of the excessive turn beyond the unlocking position, the first change-over lever only is rotationally moved, with said second change-over lever and said lock lever kept stationary. The excessive turn of said first change-over lever is detected by a switch, and when the switch is turned "On", the locking devices of other doors are also interlocked to be changed over into the unlocked state.
