To reliably maintain a close state of a door even when the direction of inertia that is applied to an inertia lever is reversed during a collision for an automobile door latch device.SOLUTION: An inertia lever 15 is held at a neutral position in which a rotation of an outside lever 14 to a release direction is allowed by a spring 26. When inertia that exceeds a set value is applied outwards, the inertia lever 15 rotates from the neutral position to one direction by a predetermined angle against a biasing force of the spring 26, and rotates to a first block position in which the rotation of the outside lever 14 to the release direction is blocked. When inertia that exceeds a set value is applied inwards, the inertia lever 15 rotates in a direction opposite to the one direction by a predetermined angle against the biasing force of the spring 26, and can rotate to a second block position in which the rotation of the outside lever 14 to the release direction is blocked.SELECTED DRAWING: Figure 6

    【課題】自動車用ドアラッチ装置において、衝突時、慣性レバーに作用する慣性方向が反転した場合であっても、ドアの閉状態を確実に維持する。【解決手段】慣性レバー15は、スプリング26によりアウトサイドレバー14のリリース方向への回動を許可する中立位置に保持されると共に、設定値を超える慣性力が外向き方向へ作用した場合には、スプリング26の付勢力に抗して、中立位置から一方向へ所定角度回動してアウトサイドレバー14のリリース方向への回動を阻止する第1ブロック位置に回動し、設定値を超える慣性力が内向き方向へ作用した場合には、スプリング26の付勢力に抗して、一方向と反対方向へ所定角度回動してアウトサイドレバー14のリリース方向への回動を阻止する第2ブロック位置に回動可能である。【選択図】 図6
