Claim:
A door lock device comprising: a latch mechanism provided at a vehicle door and engageable with or disengageable from a striker provided at a vehicle body; a lift lever for operating the latch mechanism from an engaged state in which the latch mechanism engages with the striker to a disengaged state in which the latch mechanism disengages from the striker; an open lever operated by an operation of a door opening mechanism provided at the vehicle door; a lock lever movable between an unlocked position and a locked position by an operation of a door locking/unlocking member provided at the vehicle door; an open member operated with the lock lever and movable between an unlocked position and a locked position; the open member including a link member having an operation input portion receiving an operation force from the open lever and an acting portion engageable with the lift lever, and an elastic member connecting the link member and the lock lever; wherein when the open member is in the unlocked position, the open member engages with the lift lever by an operation of the open lever in one direction thereby allowing an operation of the lift lever, and when the open member is in the locked position, the open member idly engages with the lift lever by the operation of the open lever and then automatically engages with the lift lever in the other direction by a biasing force of the elastic member to prohibit the operation of the lift lever when the open member is switched to the unlocked position from the locker position.
