Abstract:
A door lock device for a vehicle, comprising a casing (26.sub.1, 26.sub.2, 26.sub.3) fixed to a door (D.sub.F, D.sub.R) and having a bulged portion (41) which is bulged inwards of said door (D.sub.F, D.sub.R) to define an ingress passage (40) into which a striker (39) on a vehicle body (20) side enters; a latch (27) turnably supported on said casing (26.sub.1, 26.sub.2, 26.sub.3) to be brought into engagement with said striker (39) entering said ingress passage (40) for turning movement; a ratchet (28) supported on said casing (26.sub.1, 26.sub.2, 26.sub.3) for turning movement between an engaged position in which said ratchet (28) is engaged with said latch (27) and a disengaged position in which such engagement is released; an open lever (30) turnably carried on said casing (26.sub.1, 26.sub.2, 26.sub.3) and capable of receiving an operating force for releasing a locking state in which said ratchet (28) is in engagement with said latch (27); an internal operating-force inputting means (PI.sub.1, PI.sub.2, PI.sub.F, PI.sub.R) connected to said open lever (30) to transmit to said open lever (30) a door opening operation force depending on a door opening operation within the vehicle; a locked-state switch-over means (LC.sub.1, LC.sub.2, LC.sub.F, LC.sub.R) which includes an open link (31) connected at one end thereof to said open lever (30) and which is capable of switching over an unlocked state in which said ratchet (28) can be operated from the engaged position to the disengaged position in response to the turning movement of said open lever (30) following input of said door opening operation force, and a locked state in which the operation of said ratchet (28) from the engaged position to the disengaged position is impossible irrespective of the turning movement of said open lever (30) following the input of said door opening operation force, wherein said open link (31) extends along a plane perpendicular to a lengthwise direction of said ingress passage (40) and is capable of being operated within said plane, said open link being disposed sideways of said bulged portion (41) on an opposite side from an inlet (40a) of said ingress passage (40).
