In order to reliably maintain a door in a closed state even if the direction of inertia acting on an inertia lever is inverted when impact is applied, this door latch device for an automobile is configured so that, when the inertia lever 15 is moved while an open link 17 is located at an unlocking position, against the pressing force of a spring 26 from a standby position to a blocking position by inertia force exceeding a set value, the inertia lever 15 makes contact with the open link 17 to move the open link 17 from the unlocking position to a locking position, thereby preventing the open link 17 from moving from the locking position to the unlocking position, and engages with the open link 17 to prevent the open link 17 from moving from the blocking position to the standby position.

    本发明提供汽车用门锁装置,即使在受到冲击时作用于惯性操作杆的惯性方向反转的情况下,也能够可靠地维持门的关闭状态。在打开连杆(17)处于解锁位置,且惯性操作杆(15)因超过设定值的惯性力而克服弹簧(26)的作用力从待机位置移动到阻碍位置的情况下,惯性操作杆(15)与打开连杆(17)抵接,从而使打开连杆(17)从解锁位置向锁定位置移动,且阻止打开连杆(17)从锁定位置向解锁位置移动,并且惯性操作杆(15)通过与打开连杆(17)卡合而被阻止从阻碍位置向待机位置移动。
