To provide a door latch device that independently disengages the latch mechanism and switches the lock mechanism by a single motor.SOLUTION: The lock mechanism has an active lever 44 that does not regulate the forward rotation angle of a rotary cam 52 in the locked state, but regulates the forward rotation angle of the rotary cam 52 to a predetermined angle in the unlocked state. In the electric release mechanism, when the lock mechanism is locked, the rotary cam 52 is rotated from a reference position by the power of a motor in the forward direction against the urging force of a spring 54 by an angle larger than a predetermined angle, so that the latch mechanism is disengaged, and then it returns to the reference position by the urging force of the spring 54. When the lock mechanism is in the unlocked state, the rotary cam 52 is rotated by a predetermined angle in the forward direction from the reference position against the urging force of the spring 54 by the power of the motor, so that the lock mechanism is switched from the unlocked state to the locked state, and then it returns to the reference position by the urging force of the spring 54.SELECTED DRAWING: Figure 6

    【課題】単一のモータにより、ラッチ機構の噛合解除、ロック機構の切り替えを単独で行うドアラッチ装置を提供する。【解決手段】ロック機構は、ロック状態では、回転カム52の正方向への回転角度を規制しないが、アンロック状態で、回転カム52の正方向への回転角度を所定角度に規制するアクティブレバー44を有する。電動リリース機構は、ロック機構がロック状態では、回転カム52がモータの動力により基準位置からスプリング54の付勢力に抗して正方向へ所定角度よりも大きい角度回転することにより、ラッチ機構を噛合解除させた後、スプリング54の付勢力により基準位置に復帰し、ロック機構がアンロック状態で、回転カム52がモータの動力により基準位置からスプリング54の付勢力に抗して正方向へ所定角度回転することにより、ロック機構をアンロック状態からロック状態に切り替え作動させた後、スプリング54の付勢力により基準位置に復帰する【選択図】図6
