Summary:To provide a vehicle door lock device capable of preventing a door from being unlatched due to the deformation of the door caused by the collision load input.SOLUTION: A rod 30 for transmitting the operation of an outer handle 12 to an open lever 25 of a latch mechanism 20 includes a first portion 30b that extends toward a base 21 of the latch mechanism 20 and a second portion 30c that extends in the vehicle length direction from the first portion 30b. When outer panel 5 starts deforming due to the input of collision load, the second portion 30c of the rod 30 comes into contact with the base 21 of the latch mechanism 20, and the rod 30 is displaced in the opposite direction to the direction in which the latch mechanism 20 is switched from the latched state to the unlatched state.SELECTED DRAWING: Figure 3 【課題】衝突荷重入力によるドアの変形に起因して、ラッチ解除となるのを防止し得る車両用ドアロック装置を提供する。【解決手段】アウタハンドル１２の動作をラッチ機構２０のオープンレバー２５に伝達するロッド３０は、ラッチ機構２０のベース部２１に向けて上方側に傾斜して延びる第１部分３０ｂと、第１部分３０ｂから車長方向に延びる第２部分３０ｃとを備える。衝突荷重入力によるアウタパネル５の変形開始時に、ロッド３０の第２部分３０ｃがラッチ機構２０のベース部２１に当接し、ラッチ機構２０がラッチ状態からラッチ解除に切り換えられる向きとは逆向きにロッド３０が変位する。【選択図】図３
