Abstract
A door lock device includes an electrical drive source, which pivots a drive member from a predetermined neutral position, and a return urging member, which returns the drive member to the predetermined neutral position. The drive member pushes a locking lever with a first engagement portion and moves the locking lever to a lock position when the drive member moves from the predetermined neutral portion in a first direction in a state in which the locking lever is arranged at an unlock position. The drive member allows the double lock lever to move to the second position and disengages the first engagement portion from the locking lever when subsequently returned to the predetermined neutral position. The drive member pushes the double lock lever with a second engagement portion when moved again from the predetermined neutral position in the first direction.
