  On the other hand, a pressure contact blade is provided as a connection terminal for each of the lamps 30 to 32 and the connector 36. For example, in the case of the indoor lamp 30, as shown in FIGS. 11 and 13, as shown in FIG. 11 and FIG. 44 is provided in the upper part of the main body 41. In this case, as shown in FIG. 13, the press contact blade 44 is provided so that the press contact blade 44 intervenes in the path 61 of the electric wire to be connected. Although not shown, the other lamps 31 and 32 are configured in accordance with the indoor lamp 30. As for the connector 36, for example, when the press contact blade electrically connected to the connector terminal is erected on the upper portion of the connector housing and the connector 36 is assembled to the subframe 25, the press contact blade rises in the through hole 65. Configure.
[0071]
  Then, in a state where the lamps 30 to 32 and the connector 36 are assembled to the lower surface of the subframe 25, wiring is performed while pushing the electric wire (covered electric wire) constituting the wire harness 33 into the path 61. In this case, for example, in the case of the indoor lamp 30, as shown in FIG. 14, the electric wire 67 is pressed against the press contact blade 44, the covering 67a is broken, and the inner conductor 67b of the electric wire 67 contacts the press contact blade 44. Become. That is, the indoor lamp 30 and the wire harness 33 are electrically connected by press-connecting the press-contact wave 44 of the indoor lamp 30 to the electric wire 67 of the wire harness 33 in this way. Although not shown, the other lamps 31 and 32 and the connector 36 are configured in the same manner as the indoor lamp 30.
[0072]
  According to such a structure, when the electric wire 67 is wired along the path as described above, the electric wire 67 is press-connected to the press contact blade 44, and further, the electric wire 67 is held in a state where the press contact blade 44 is bitten. . That is, simultaneously with the wiring harness 33 being routed, each of the lamps 30 to 32 and the like and the wire harness 33 can be electrically connected, and the wire harness 33 can be fixed to the subframe 25. Therefore, there is a merit that workability when wiring the wire harness 33 to the sub frame 25 can be remarkably improved.
[0073]
  Further, if the electric wire 67 is pulled out and a new electric wire is routed again along the path 61, the wire harness 33 can be easily routed, so that there is an advantage that the maintainability is good.
[0074]
  In the above-described configuration, for example, as shown in FIG. 15, a wiring device 70 including a head 71 for leading out the electric wire 67 and a roller 72 for pressing the derived electric wire 67 is used. As shown in FIG. 4, the wiring device 70 is moved along the path 61, and the wire harness 33 is automatically routed in the subframe 25 while the electric wire 67 led out from the head 71 is pushed into the path 61 by the roller 72. be able to.
[0075]
  (4) Furthermore, as another structure for routing the wire harness 33, each wire constituting the wire harness 33 is composed of a conductive wire (a wire without covering), and the wire harness 33 is directly connected by energizing each conductive wire. It is also possible to adopt a structure in which wiring is performed while being embedded in the subframe 25.
[0076]
  That is, as shown in FIG. 16, a certain range is connected to the power source 74 while the conductor 68 is wired along a predetermined path, and the conductor 68 is made of an insulator while energizing this range. To the subframe 25. In this case, since the subframe 25 is made of a resin such as ABS or PE as described above, the subframe 25 is melted by heat generated by energization, and the conductor 68 is fixed in a state where it is embedded in the subframe 25. Will be. In the case of this structure, for example, the conducting wire 68 is exposed on the surface (lower surface) of the subframe 25 at the assembly position of the lamps 30 to 32 and the like of the subframe 25, and according to the structure shown in FIG. Each of the lamps 30 to 32 and the wire harness 33 are electrically connected by bringing a leaf spring-like terminal such as each of the lamps 30 to 32 into contact with the conductor 68.
[0077]
  According to this structure, there is an advantage that the wiring harness 33 can be routed and the wire harness 33 can be fixed to the subframe 25 at the same time.
[0078]
  Moreover, the weight reduction of the sub-frame unit 11 is achieved by the fact that the wire harness 33 is composed of the conductive wires 68 as described above, and that a dedicated fixing member for fixing the wire harness 33 to the sub-frame 25 is unnecessary. There is merit that we can contribute to.
[0079]
  In addition, since the wire harness 33 can be routed with respect to the subframe 25 by an arbitrary route, for example, the subframe 25 can be used in common between vehicle types having different routing routes of the wire harness 33. Therefore, the manufacturing cost of the sub-frame 25 can be suppressed, and there is also an advantage that it can contribute to the cost reduction of the unit member 10.
[0080]
  In addition, as a modification of this structure, for example, each electric wire of the wire harness 33 is composed of a normal covered electric wire, and the inner conductor is exposed by removing the electric wire covering at a specific location, and the exposed portion is energized. You may make it fix in the state which embedded some electric wires in the sub-frame 25. FIG.
[0081]
  When the subframe 25 is made of, for example, a metal or a resin material that is not easily melted, as shown in FIG. 17, a fixing member 75 made of a thermoplastic resin that melts relatively easily by energization is attached to the subframe 25, You may make it fix the conducting wire 68 with respect to this fixing member 75. FIG.
[0082]
  Further, when the conductor 68 is wired, a presser member 73 made of a conductor such as metal is used as the presser member 73, and a part of the conductor 68 and the presser member 73 are connected to a power source 74 as shown in FIG. The operation may be performed so that a current flows through the conductor 68 when the conductor 68 is pressed by the pressing member 73.
[0083]
  C. About the structure of each lamp 30-32
  The indoor lamp 30 will be described as an example. As shown in FIG. 19, the main body 41 of the indoor lamp 30 is formed smaller than the opening 51 of the molded ceiling 13, while the lamp cover 42 is formed larger than the opening 51. As shown in the figure, when the automobile ceiling is assembled, the molded ceiling 13 is assembled with the lamp cover 42 removed, and then the lamp cover 42 is opened from the lower side of the molded ceiling 13 as shown in FIG. It can also be configured to be attached to the main body 41 via 51. In this case, as shown in FIG. 19, a hook 42 b is provided on the lamp cover 42, and the hook cover 42 is engaged with a locking portion (not shown) of the lamp cover 42 so that the lamp cover 42 is attached to the main body 41. Configure.
[0084]
  Also in this configuration, the edge of the opening 51 can be covered with the lamp cover 42, so that the appearance from the indoor side can be kept good. Although the indoor lamp 30 has been described as an example here, the other map lamps 31 and vanity lamps 32 can be configured in the same manner.
[0085]
  D. Other configurations
  (1) The subframe unit 11 and the sunroof unit 12 may be configured to be separately assembled to the body ceiling 2 without being unitized as the unit member 10. In the case of this configuration, the subframe unit 11 constitutes a unit member according to the present invention.
[0086]
  (2) In addition to the lamps 30 to 32, the electrical component to be assembled to the subframe 25 may be an audio device such as an air cleaner or a speaker.
[0087]
