Abstract: A door lock system for a vehicle includes a) a latch mechanism which is adapted to a vehicle door and which holds the vehicle door to a vehicle body, b) an open link which is engagable and disengagable with the latch mechanism, c) a swing lever which is connected to the open link, d) an electric driving source having a gear member, and e) a rotary gear member which is arranged between the swing lever and the electric driving source so as to be meshed with the gear member of the electric driving source. The rotary gear member is directly and engagably connected to the swing lever.

Abstract: A door lock system for a vehicle includes a latch mechanism, an open link, an inside lever and a cancel lever. The latch mechanism is adapted to a vehicle door and latches the vehicle door to a vehicle body. The open link is engagable and disengagable with the latch mechanism. The inside lever is adapted to an inside handle of the vehicle door and is engagable with the open link. The cancel lever is connected to the open link and is arranged between the inside lever and the open link so as to be engagable with the inside lever when the open link is disengaged from the latch mechanism.

Abstract: A door lock device includes a base plate 2 having horizontal wall 21 connected to a door lock body 31 and vertical wall 22 perpendicular to the horizontal wall 21, a rotation lever 49 rotatably supported to the vertical wall 22, a key lever 47 rotatably supported to a housing 64 of an actuator 6 which is secured to the vertical wall 22, and a connecting lever 48 having one end and the other end, one end being coupled to the rotation lever 49 after rotation of one end to the rotation lever 49, the other being coupled to the key lever 47 after rotation of the other end to the key lever 47, the connecting lever 48 being in parallel and close to the connecting vertical wall 22 of the base plate 2.
