Specifically, the second switch 14 detects whether the rotational position of the latch 43 is located at a position other than the fully latching position. In this detection, the second switch 14 detects whether the rotational position of the latch 43 is nearer to the unlatching position than when it is at a position between the fully latching position and the half latching position.
  • the second switch 14 detects that the rotational position of the latch 43 is located at a position other than the fully latching position (that the door is half-shut or open), a room lamp of the vehicle is turned on. In contrast, when the rotational position of the latch 43 is located at the fully latching position (the door is completely shut), the second switch 14 turns off the room lamp of the vehicle.

  • second internal wiring that electrically connects to the second switch 14 is changed to the harness plate 8 from a conventional switch plate (a second switch plate). Consequently, the second internal wiring can be extremely smaller than conventional wiring, and the shape of the wiring can be simplified.
  • the yield of the switch plate 7 is improved as compared with the conventional one, so that size reduction and cost reduction for a switch plate embedded in the vehicle door locking device 1 are made possible. Not only that, size reduction and cost reduction for the vehicle door locking device 1 can be facilitated.
  • the harnesses 81 and 82 in the harness plate 8 are mounted on the groove section 831 of the harness holding section 83 so as to be held alongside each other in the vehicle inside-to-outside direction thoroughly from the top portion to the bottom portion of the inclined part 10c in the upper-end side wall part 10b of the casing 10. Consequently, the height positions of the harnesses 81 and 82 can be set as low as possible without imposing excessive torsional loads on the harnesses 81 and 82. As a result, the height position of the upper-end side wall part 10b of the casing 10 extending along the harness plate 8 can be set as low as possible. Thus, size reduction of the casing 10 and consequent size reduction of the vehicle door locking device 1 can be further facilitated.
  • the terminals 81a and 82a and the vicinities thereof of the respective harnesses 81 and 82 are inserted through the insertion holes 832a and 832b of the insertion holding section 832, respectively, in the inside-to-outside direction of the vehicle so that the terminals 81a and 82a are held so as to be able to come into abutment with the respective terminals of the second switch 14.
  • the second switch 14 held by the switch holding section 833 of the harness plate 8 is inserted through the insertion hole 41a formed in the body 41 of the latch mechanism 4 to be placed near the outer circumference of the latch 43.
  • the second switch 14 mounted on the switch holding section 833 is enabled to detect the rotational position of the latch 43 without complication of the structure of the harness plate 8, for example, a structure thereof in which the second switch 14 bypasses the body 41 of the latch mechanism 4 to be placed near the outer circumference of the latch 43.
  • the present invention is not limited to this.
  • the number of harnesses that are collectively mounted on the harness plate 8 may be multiple (two or more).
  • the number of conducting plates of the switch plate 7 may be multiple (two or more) so as to agree with the number of harnesses in the harness plate 8.
  • the two or more harnesses that are collectively mounted on the harness plate 8 may include a harness that connects to an electronic component other than the second switch 14.
  • the present invention is not limited to this.
  • the two or more harnesses that are collectively mounted on the harness plate 8 may be arranged alongside one another in the vehicle inside-to-outside direction all along the upper-end side wall part 10b of the casing 10. That is, the harness holding section 83 may hold the two or more harnesses alongside one another in the vehicle inside-to-outside direction all the way through the switch-side groove part 831b and the intermediate groove part 831c.
  • the vehicle door locking device according to the present invention is advantageous to size reduction and cost reduction for a vehicle door locking device that includes a plurality of electronic components, and is particularly suitable for a vehicle door locking device that can improve the yields of wiring components embedded therein.
