Description

  The present invention relates to an improvement in a vehicle door lock device provided on a vehicle body and a door.

  2. Description of the Related Art A vehicle door lock device is known in which a latch unit operates via a rod by pulling a door outer handle, and a door latch is released (see, for example, Patent Document 1 (FIG. 8)).

  The vehicle door lock device disclosed in Patent Document 1 is provided with a latch unit capable of latching and unlatching motion, and a door outer handle for performing a latch releasing operation of the latch unit. The latch unit performs a latching and unlatching motion with respect to a striker provided in the vehicle body.

  In general, by operating the door outer handle, the rod connected to the door outer handle is pushed down, and when the rod pushes down the latch release lever of the latch unit, the latch of the latch unit is released. One end of the rod is connected to the release lever, and the release lever moves as the rod moves.

  By the way, the door of a motor vehicle may be deformed and recessed due to a side collision, for example. When the door is deformed, the door outer handle is pulled toward the hollow side, and the rod is also pulled by following the door outer handle. The pulled rod can be deformed in contact with the latch unit or a sash disposed in the vicinity of the latch unit, and can be displaced in the direction of pushing down the release lever by twisting the connecting portion with the latch release lever.

  Further, as another case, when the rod is pulled by the door being deformed and recessed during a side collision, the release lever may be displaced in the pulling direction. Thereafter, the recess of the door is pushed back outward in the vehicle width direction by a springback action. As a result, the door outer handle and the rod are pushed back and can be displaced in the direction of pushing down the release lever.

  When the release lever is pushed down at the time of a side collision, it is disadvantageous for improving the occupant protection performance in the vehicle. As a countermeasure, it is conceivable to separately provide a latch release prevention mechanism at the time of a side collision in the vehicle door lock device. However, the mechanism for preventing latch release at the time of a side collision tends to be complicated and expensive.
