Document Type and Number:
Japanese Patent JP6708489
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely prevent opening of a door in which an impact is applied.SOLUTION: A door lock device 10 includes: a latch mechanism 18 capable of engaging/disengaging a striker; an open lever 55 rotating being interlocked with an operation of a door handle; a transmission member 27 which can oscillate between an unlock position and a lock position; and a spring member 48 for energizing the transmission member 27 toward the unlock position from the lock position. When an inertia force which is equal to or greater than a set value acts on the transmission member 27, the spring member 48 permits the movement of the transmission member 27 toward the lock position from the unlock position. A spring operation part (width W of a part 31 to be guided) is provided which expands/contracts the spring member 48, when the transmission member 27 advances/retreats by the rotation of the open lever 55.SELECTED DRAWING: Figure 3A
