And the wire harness 33 is electrically connected to the lamps 30 to 32 and the like. Thereby, the sub-frame unit 11 is completed. In the assembly of the sub-frame unit 11, for example, the sub-frame 25 is fixed to a workbench or the like in a state where the sub-frame 25 is turned upside down, and in this state, the wiring harness 33 and the lamps 30 to 32 are assembled. Thus, the work can be efficiently performed in a comfortable posture.

When the subframe unit 11 is completed,
As shown in FIG. 3E, the sunroof unit 12 separately assembled is mounted on the upper surface of the subframe of the subframe unit 11. When the sunroof unit 12 is assembled in this manner, the press contact terminal and the internal conductor of the wire harness 33 (branch portion 34) come into contact as described above, and the sunroof unit 12 and the wire harness 33 are electrically connected. Thereby, the unit member 10 is completed.

In the assembly work (main work) of the automobile ceiling,

When the assembly of the molded ceiling 13 is completed, finally, the sun visor 14 and the assist grip 15 are fixed to the body ceiling 2 from outside (inside the room) of the molded ceiling 13 with bolts. This completes the work of assembling the car ceiling.

According to such a structure for mounting the automobile ceiling, when assembling the automobile ceiling, the sunroof unit 12, the various lamps 30 to 32, The wiring harness 33 for these electrical components is connected to the body ceiling 2 at a time.
Can be assembled. As a result, the number of man-hours required for assembling the vehicle ceiling can be significantly reduced as compared with the related art, and the work in the upward posture can be reduced accordingly. It can be dramatically improved.

Further, it is expected that the occurrence of defective assembly can be suppressed by reducing the work in the upward posture. In particular, the electrical connection between the electrical components such as the lamps 30 to 32 and the wire harness 33 can be made before the assembly to the body ceiling 2, so that the connectors are connected in an upward position. These electrical connection operations can be performed more accurately and reliably as compared to
Occurrence of a connection failure between the wire harness 33 and the wire harness 33 can be reliably prevented.

In the above-described structure for mounting the automobile ceiling,
There is a concern that the provision of the sub-frame 25 may reduce the indoor space. However, as described above, the sub-frame 25 is formed in a thin plate shape, and the wire harness 33 is provided.
The sub-frame unit 11 is configured not to be bulky by using a flat cable. Therefore, there is almost no effect on the indoor space,
An indoor space can be secured as in the conventional case.

By the way, various modifications are conceivable for the above-described structure for assembling the ceiling of an automobile. For example, a structure as described below can be adopted.

A. Regarding the subframe 25 The subframe 25 may be made of a metal material. However, in this case, it is desirable to reduce the weight by using a lightweight metal material such as aluminum. In addition,
The sub-frame 25 does not necessarily have to be in the form of a thin plate. However, if the occupied space of the sub-frame 25 is large, the indoor space may be affected. .

In a vehicle without a sunroof, the opening 26 for the sunroof is not required in the subframe 25.
For example, taking into account only the mounting position of each of the lamps 30 to 32, a “T” -shaped sub that includes a front portion extending in the width direction between the front pillars and a portion extending toward the rear of the vehicle body 1 from an intermediate position therebetween. The frame 25 may be configured. The shape of the sub-frame 25 may be appropriately formed according to the mounting position of the electrical component and the wiring route of the wire harness.

Center part 2 in subframe 25
The position of 5c may be changed in the front-back direction of the vehicle body 1.

That is, although the interior lamp 30 is assembled to the center portion 25c as described above, the position of the interior lamp 30 is different between the vehicle body 1 having a sunroof and the vehicle body 1 not having the sunroof even in the same model. Therefore, by configuring so that the position of the center portion 25c can be changed as described above, the subframe 25 can be shared between the vehicle body 1 with the sunroof and the vehicle body 1 without the sunroof.

Specifically, it can be configured as follows. That is, as shown in FIG. 7, for example, as shown in FIG. 7, a pair of bolt holes 55a and 55b for mounting the center portion corresponding to the vehicle body 1 with the sunroof and the vehicle body 1 without the center portion are formed in the longitudinal direction of the side portion 25b. It is formed at predetermined intervals in the direction (the front-back direction of the vehicle body 1). Then, as shown in FIG. 8, a bolt 57 is passed through a mounting hole 56 formed at both ends of the center portion 25c, and this is selectively screwed into the bolt hole pair 55a or 55b.
According to this, the position of the center portion 25c can be changed with a simple configuration. As another configuration, as shown in FIG. 9, a side portion 25b is formed in a U-shaped cross section, and an opening pair corresponding to a vehicle body 1 with a sunroof and a vehicle body 1 without the sunroof in the longitudinal direction of the side surface of the side portion 25b. 58a,
58b are formed at a predetermined interval, and projections 59 are provided at both ends of the center portion 25c, and these projections 59 are fitted into the pair of openings 58a or 58b to form the center portion 2b.
5c may be configured to be attached to the side portion 25b. According to this, the side portion 25 can be used without using bolts.
The center portion 25c can be assembled to the sub-frame 25b, and the sub-frame 25 can be easily assembled.

B. Wiring and Electrical Connection Structure of the Wire Harness 33 A configuration in which a general wire harness is used as the wire harness 33 and the lamps 30 to 32 and the like and the wire harness 33 are electrically connected by fitting connectors. Can also be adopted.

In the above case, for example, a groove-like path for arranging the electric wires constituting the wire harness 33 is formed in the sub-frame 25, and each electric wire is pressed into this path and held. You may. In this way, the wiring of the wire harness 33 and the fixing of the wire harness 33 to the sub-frame 25 can be performed simultaneously,
Workability when wiring the harness is improved.

Further, it is also possible to adopt a configuration in which a press contact blade is provided on an electrical component such as the indoor lamp 30 and the electric component is press connected to the wire harness 33. Specifically, it can be configured as follows.

That is, as shown in FIGS. 10 and 12, a groove-like path 61 for arranging electric wires is formed on the upper surface of the sub-frame 25, and the lamps 30 to 32 and the connector 36 are formed on this path. Are formed at positions corresponding to the mounting locations of the above.

On the other hand, each of the lamps 30 to 32 and the connector 36 is provided with a pressure contact blade as a connection terminal. For example, in the case of the interior lamp 30, as shown in FIGS. 11 and 13, when the interior lamp 30 is mounted at a predetermined mounting position of the sub-frame 25, the press-contact blade is raised so as to rise into the through hole 62. 44 is provided on the upper part of the main body 41. In this case, as shown in FIG. 13, the press contact blades 44 are provided so that the press contact blades 44 intervene in the paths 61 of the electric wires to be connected. Although not shown, the other lamps 31 and 32 have a configuration similar to that of the indoor lamp 30. For the connector 36, for example, a press-contact blade electrically connected to the connector terminal is provided upright on the connector housing, and the connector 36
Is assembled to the sub-frame 25 so that the press contact blade rises in the through hole 65.

Then, in a state where the lamps 30 to 32 and the connector 36 are assembled on the lower surface of the sub-frame 25, the electric wires (covered electric wires) constituting the wire harness 33 are laid while being pushed into the path 61. In this case, for example, in the case of the interior lamp 30, the electric wire 67 is pressed against the press-contact blade 44 as shown in FIG.
Is broken, and the inner conductor 67b of the electric wire 67 comes into contact with the press contact blade 44. That is, in this way, the interior lamp 3
The interior lamp 30 and the wire harness 33 are electrically connected by press-connecting the 0 pressure welding wave 44 to the electric wire 67 of the wire harness 33. Although not shown, the other lamps 31 and 32 and the connector 36 are configured in the same manner as the indoor lamp 30.

According to such a structure, if the electric wires 67 are laid along the path as described above, the electric wires 67
4 and is held in a state where the electric wire 67 is bitten by the press contact blade 44. That is, the wire harness 33
At the same time as wiring, the lamps 30 to 32 and the like and the wire harness 33 are electrically connected, and the wire harness 33 can be fixed to the subframe 25.
Therefore, the wiring harness 3
There is a merit that workability at the time of wiring 3 can be remarkably improved.

Further, if the electric wire 67 is pulled out and a new electric wire is laid again along the route 61, the wire harness 33 can be easily re-routed.

In the above configuration, for example, as shown in FIG.
And a wiring device 70 provided with a roller 72 for pressing the derived electric wire 67. The wiring device 70 is moved along the path 61 as shown in FIG. The wire harness 33 can be automatically routed to the sub-frame 25 while pushing the 67 into the path 61 by the roller 72.

Further, as another structure for arranging the wire harness 33, each electric wire constituting the wire harness 33 is composed of a conductor (uncovered wire), and a current is applied to each conductor to directly connect the wire harness 33. It is also possible to adopt a structure in which wiring is performed while being embedded in the sub-frame 25.

As a modification of this structure, for example, each electric wire of the wire harness 33 is formed of a normal coated electric wire, the coating of the electric wire is removed at a specific portion to expose the inner conductor, and the exposed portion is energized. By doing so, a part of the electric wire may be fixed while being buried in the sub-frame 25.

When the sub-frame 25 is made of, for example, a metal or a resin material which is hardly melted, as shown in FIG. 17, a fixing member 75 made of a thermoplastic resin which is relatively easily melted by energization is used. Attached to
The conducting wire 68 may be fixed to the fixing member 75.

When the conductor 68 is laid, a pressing member 73 made of a conductor such as a metal is used as the pressing member 73. As shown in FIG.
3 is connected to a power supply 74, and a lead 68 is
The operation may be performed such that a current flows through the conductive wire 68 when is pressed.

C. The structure of each of the lamps 30 to 32 will be described by taking the interior lamp 30 as an example. As shown in FIG.

As shown in FIG. 20, the lamp cover 42 may be attached to the main body 41 from below the molded ceiling 13 through the opening 51. In this case, as shown in FIG.
2, a hook 42b is provided, and the hook 42b is engaged with a locking portion (not shown) of the lamp cover 42 to attach the lamp cover 42 to the main body 41.

Also in the case of this configuration, the edge of the opening 51 can be covered and hidden by the lamp cover 42, so that the appearance from the indoor side can be kept good. Here, the indoor lamp 30 has been described as an example, but other map lamps 31 and vanity lamps 32 can be configured similarly.

D. Other Configurations Subframe Unit 11 and Sunroof Unit 1
2 may 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.

The electrical components to be mounted on the sub-frame 25 may be, for example, audio devices such as air purifiers and speakers, in addition to the lamps 30 to 32.
