Title
(EN) Vehicle door lock device
Abstract
(EN)

A vehicle door lock device includes a latch mechanism having a latch and a pawl, and a lock mechanism having an open lever linked with the pawl. The lock mechanism is combined with the latch mechanism. A latch-side axial support portion is provided in a latch housing of the latch mechanism. The latch-side axial support portion rotatably supports a coil portion of a pawl spring for biasing the pawl toward a default position. A lock-side axial support portion is provided in a lock housing of the lock mechanism. The lock-side axial support portion rotatably supports a coil portion of an open lever spring for biasing the open lever toward a default position. At least part of the latch-side axial support portion overlaps with the lock-side axial support portion, so that pulling out of the open lever spring is prevented by means of the latch-side axial support portion.
