ABSTRACT:
A power door lock device comprises a latch plate pivotal about a first axis to assume an open position, a half-latch position and a full-latch position; a sub-lever pivotal about a second axis which is in parallel with the first axis; and a close lever pivotal about the second axis. The sub-lever has an engaged edge and is pivotally connected through a link to the latch plate, so that when the sub-lever is pivotal about the second axis to assume first, second and third angular positions, the latch plate takes the open position, half-latch and full-latch positions respectively. The close lever has an engaging edge which, when the close lever is pivoted from an inoperative position to an operative position, is brought into abutment with the engaged edge of the sub-lever to pivot the sub-lever from the second position to the third position. An electric drive device is used for forcing the close lever to pivot between the inoperative and operative positions. The latch plate, the link and the sub-plate are so arranged that the second angular position of said sub-lever is positioned near the first angular position of the same as close as possible.
