Abstract

[Problem] To provide a door locking device for a vehicle, wherein it is possible to reduce production costs while preventing the door from opening unintentionally when the vehicle is in a collision and while eliminating having to redo an unlocking operation when the unlocking operation and a door opening operation overlap. [Solution] A door locking device (1) for a vehicle, wherein: a third lever (50) is capable of being displaced to a third position and a fourth position, the third position being a position in which a second lever (30) capable of swinging from a first position to a second position as a consequence of an inertial force (F1) surpassing a set value and acting on the second lever (30) is allowed to be at the first position and the second position, and the fourth position being a position in which the second lever (30) is held at the second position; and a fork (11) can be switched to an unlatch state when the third lever (50) is at the third position, while the fork (11) cannot be switched to the unlatch state when the third lever (50) is at the fourth position. When a first lever (13) attempts to swing while the second lever (30) is at the second position, a holding means (60) allows the first lever (13) to swing while holding the second lever (30) at the second position regardless of the position of the third lever (50).
