Summary:[Problem] To provide a door lock device with which it is possible to prevent a door latch being disengaged by a lateral impact. [Solution] With this door lock device, even if a vehicle is laterally impacted and an open lever is pressed against the door inner face side, a latch part of the open lever makes contact with a restriction part which is disposed in a metal plate, and it is possible to restrict the forward movement of the open lever. It is thus possible to prevent a door latch being disengaged by a vehicle lateral impact which could have been a problem with a conventional door lock device. Cette invention concerne un dispositif de serrure de portière permettant d'empêcher le désaccouplement d'un loquet de portière par impact latéral. Ledit dispositif de serrure de portière dont une partie formant loquet du levier d'ouverture entre en contact avec une partie de confinement ménagée dans une plaque métallique et permet de limiter le mouvement en avant du levier d'ouverture, même en cas d'impact latéral d'un véhicule entrainant la poussée du levier d'ouverture contre la face interne de la portière. Contrairement aux dispositifs de serrure de portières classiques, le dispositif selon l'invention permet ainsi d'empêcher le désaccouplement d'un loquet de portière par impact latéral du véhicule.
