The door lock system comprises a door latch device 104, having a locking/unlocking lever 102, and an electric actuator including a worm wheel 3 driven by a reversible electric motor 1 to rotate in both directions from a neutral position. An operation lever 6 is linked to the (un)locking lever 102 to assume locking and unlocking positions when the lever 102 assumes lock and unlock positions respectively. The operation lever 6 has a projection 6b with which a projection 3a on the worm wheel 3 is engageable to pivot the lever 6 to the locking and unlocking positions upon rotation of the work wheel. An antitheft lever 9 has an engaging pin 9b slidably engaged with a cam groove 4 in the worm wheel 3. In response to the rotation of the worm wheel, the antitheft lever 9 is pivoted between a cancelling position wherein it is kept away from the travelling path of the operation lever 6, and a theft protection position, wherein at least a portion of the antitheft lever 9 is positioned on the travelling path of the operation lever 6. <IMAGE> |
