In the rail member 32, the drain space 32C is located on one side of the belt housing space 32B with respect to the cross direction Y (the side opposite to the slide space 32A). The drainage space 32C is formed as a space surrounded by the main body 32aa of the bottom wall 32a, the folded portion 32ab, the vertical wall 32ba of the wall 32b, and the like. Water that has entered the inside of the vehicle body B through the opening RPO is drained through the drainage space 32C.

The wiring space portion 32D is a space portion formed between the guide wall portion 32f and the bottom wall portion 32a constituting the wiring wall portion and in which the wiring material 5 is routed along the slide direction X (Fig. 8, see FIG. 9, etc.). In the rail member 32, the cabling space 32D is located below the slide space 32A with respect to the height direction Z with the guide wall 32f therebetween. The cabling space portion 32D is formed as a space surrounded by the main body portion 32aa of the bottom wall portion 32a, the wall portion 32c, the wall portion 32d, the guide wall portion 32f, and the like. With this configuration, the cabling space 32D is formed as a cabling-only space separated from the slide space 32A by the guide wall 32f. The wiring member 5 is laid in the wiring space 32D along the sliding direction X and placed on the main body portion 32aa of the bottom wall portion 32a facing the wiring space 32D. Here, the wiring member 5 configured by the flat cable is mounted and wired on the main body portion 32aa so that the thickness direction is along the height direction Z. As shown in FIG. Then, the wiring member 5 is pulled out from or accommodated in the power supply mechanism 6 as the sunroof main body 2 slides while being routed in the wiring space 32D.

The slit portion 32E is a space formed along the sliding direction X and positioned adjacent to the guide wall portion 32f along the cross direction Y. As shown in FIG. The slit portion 32E is positioned in the rail member 32 between the tip of the guide wall portion 32f in the cross direction Y and the wall portion 32c. That is, the slit portion 32E is formed by the tip of the guide wall portion 32f in the cross direction Y and the wall portion 32c, and is formed as a space portion that communicates the slide space portion 32A and the wiring space portion 32D. One end 5a of the wiring member 5 is routed across the sunroof main body 2 side and the wiring space portion 32D side through the slit portion 32E with the guide wall portion 32f interposed therebetween (see FIG. 8). . One end 5a of the wiring member 5 is routed from the wiring space 32D to the sunroof main body 2 through the slit 32E and the slide space 32A. With this configuration, the slit portion 32E can allow the one end portion 5a to move along the sliding direction X as the sunroof body 2 slides.

In the sunroof 1 configured as described above, when the sunroof main body 2 slides from the fully closed position side to the fully open position side, the sunroof main body 2 and one end portion 5a of the wiring member 5 supply power along the sliding direction X. It slides to the side approaching the mechanism 6 (that is, to the fully open position side). At this time, one end portion 5a of the wiring member 5 moves along the sliding direction X in the slit portion 32E as the sunroof body 2 slides, thereby allowing the end portion 5a to move. . Then, in the sunroof 1 , the wiring material 5 wired in the wiring space portion 32</b>D is wound along the sliding direction X by the power supply mechanism 6 . As a result, the sunroof 1 can absorb the extra length of the wiring member 5 by the power supply mechanism 6 . On the other hand, in the sunroof 1, when the sunroof main body 2 slides from the fully open position side to the fully closed position side, the sunroof main body 2 and one end 5a of the wiring member 5 are separated from the power supply mechanism 6 along the sliding direction X. side (that is, the fully closed position side). At this time as well, one end 5a of the wiring member 5 moves along the sliding direction X in the slit portion 32E as the sunroof body 2 slides, so that the movement of the end 5a is permitted. be. Then, in the sunroof 1, the wiring material 5 wired in the wiring space portion 32D is pulled out along the sliding direction X from the power feeding mechanism 6. As shown in FIG. In this manner, the sunroof power supply structure 100 can constantly supply power (supply power) to the sunroof main body 2 via the wiring members 5 .

The sunroof 1 and the power supply structure 100 for the sunroof described above are arranged on the sunroof main body 2 which is slidably supported along the sliding direction X via the first slider 34 and the second slider 35 with respect to the rail member 32 . One end 5a of the cable 5 is electrically connected. The power supply structure 100 for the sunroof holds the other end 5b of the wiring member 5 by the power supply mechanism 6 and supplies power, and pulls out and stores the wiring member 5 as the sunroof main body 2 slides. . With such a configuration, in the sunroof power supply structure 100, the wiring space portion 32D is formed between the guide wall portion 32f and the bottom wall portion 32a in the rail member 32. As shown in FIG. In the sunroof power supply structure 100, the wiring material 5 is laid along the sliding direction X in the wiring space 32D dedicated to wiring. With this configuration, the sunroof power supply structure 100 can constantly supply power while allowing the wiring member 5 to follow the sliding movement of the sunroof main body 2 in the limited space between the roof panel RP and the roof liner RL. In addition, the power supply structure 100 for the sunroof can suppress the wiring member 5 from interfering with the first slider 34, the second slider 35, and other structures. It is possible to suppress scraping of the rope material 5 and the like. As a result, the sunroof 1 and the power supply structure 100 for the sunroof can properly route the wiring member 5 .

Here, the sunroof 1 and the power supply structure 100 for the sunroof described above are arranged such that one end 5a of the wiring member 5 slides along the sliding direction X as the sunroof body 2 slides. Movement can be permitted by the slit portion 32E. As a result, the sunroof 1 and the power supply structure 100 for the sunroof can suppress the application of excessive stress to the wiring member 5, and the wiring member 5 can be routed more appropriately.
