Claim 7:
8. The door lock device according to claim 2, further comprising:
a lock lever configured to switch between
an unlocking biased position where the open link is positioned at the unlocking position, and
a locking biased position where the open link is positioned at the locking position; and

an anti-panic lever configured to
displace relatively to the lock lever,
be displaceable between a cooperating position and an anti-panic position, and
communicate a displacement of the lock lever to the open link, when the anti-panic lever is at the cooperating position, wherein

when the outer lever is moved while the lock lever is at the locking biased position and the open link is at the locking position, the anti-panic lever
moves relatively from the cooperating position to the anti-panic position, thereby permitting the lock lever to become displaced to the unlocking biased position, and
returns from the anti-panic position to the cooperating position when the operation of the outer lever is ended, and

when the inertial force causes the inertial lever to swing the open link, the open link and the anti-panic lever are caused to swing integrally, while the lock lever is kept at the unlocking biased position.
