Abstract
A door lock mechanism includes a lock claw, a spring attached to the lock claw for urging the same in a direction toward a lock state, a lock release operation piece linked to the lock claw for moving the lock claw in a direction toward a lock release state against a force of the spring when a lock release operation is performed, and a damping device for applying a damping force to the lock claw when the lock release operation is canceled. The lock release operation piece returns the lock claw to the lock state with the force when the lock release operation is canceled. The lock release operation piece is arranged to be separated from the lock claw when the lock claw returns from the lock release state to the lock state with an external force applied to the lock claw.
