To provide a door latch device that can prevent a door from being opened unexpectedly upon receipt of a strong impact.SOLUTION: A door latch device 10 includes: a fork 26; a claw 27; a movable member 33 that causes, upon movement thereof in a first direction A, the claw 27 in an engaged position to rotate to an unengaged position; an electric motor 31 that moves the movable member 33 in the first direction A and a second direction B; and a control unit 70 that controls the electric motor 31. The control unit 70 executes emergency energizing processing to energize the electric motor 31 so as to restrict the movement of the movable member 33 in the first direction A when a signal indicating a shock of a set value or higher is input from a shock detection unit 75 or a predictive shock detection unit 76.SELECTED DRAWING: Figure 5

    【課題】強い衝撃が加わったときの意図しないドアの開放を防止できるドアラッチ装置を提供する。【解決手段】ドアラッチ装置10は、フォーク26と、クロー27と、第1の向きAへの移動によって係止位置のクロー27を非係止位置に回転させる可動部材33と、第1の向きAと第2の向きBへ可動部材33を移動させる電動モータ31と、電動モータ31を制御する制御部70とを備える。制御部70は、衝撃検出部75又は予測衝撃検出部76から、設定値以上の衝撃を示す信号が入力されると、第1の向きAへの可動部材33の移動を規制するように、電動モータ31に通電する非常通電処理を実行する。【選択図】図5
