Door lock device for vehicle

Abstract

The vehicular door lock device includes a casing fixed to a door and having a bulged portion defining an ingress passage receiving a striker on a vehicle body. A latch is supported on the casing for engagement with the striker for turning movement. A ratchet on the casing is for engagement and disengagement with and from the latch. An open lever is turnable on the casing and receives an operating force for releasing a locking state having the ratchet engaged with the latch. An internal operating-force inputting device transmits to the open lever a door opening operation force depending on the door opening operation within the vehicle. A locked-state switch-over device has an open link connected at one end to the open lever and switches over to an unlocked state to operate the ratchet from the engaged position to the disengaged position in response to the open lever turning, and a locked state inhibiting the ratchet from going to the disengaged position, irrespective of the turning movement of the open lever. The open link extends along a plane perpendicular to a lengthwise direction of the ingress passage and, is disposed sideways of the bulged portion on an opposite side from an inlet of the passage. The space occupied by the door lock device in the direction to avoid interference with a glass sash, along the thickness of a door can be small, and the door internal structure and thickness can be designed as desired.
