Therefore, the sunshade used in the conventional glass sunroof can be arbitrarily provided without providing the sunshade, and the complexity of operating the sunshade can be eliminated.

Further, since no obstructive lead wire is protruding from the end surface 15 of the sunroof glass 3, the end surface 15 can be easily waterproofed. In addition, the routing of the wiring by the connecting wire 33 from the lead wire 24 to the brush 29 is fixed along the stay 8, so that the routing and the fixing of the wiring can be easily and reliably performed without separately providing a bracket. You can Since the lead wire 24 is taken out from the inner edge of the sunroof glass 3 to some extent, it is not necessary to provide the liquid crystal sheet 23 up to the end surface 15 of the sunroof glass 3 and take it out from the end surface 15. Can be eliminated to the full extent of the peripheral portion of the sunroof glass 3, and the cost of parts can be reduced.

FIG. 3 is a view similar to FIG. 2 showing a second embodiment according to the present invention, in which the same parts as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted. In the second embodiment, the take-out hole 35 is provided in the glass holder 7 and, as shown in the drawing, the glass holder 7 of the front stay 8 is provided.
Since the connector 32 is provided so as to be covered by the lower surface of the sunroof glass 3 and the glass holder 7 because it is provided in the vicinity of the mounting portion, the connector 32 is cut off from the outside, and the connector 32 is It is possible to suitably prevent rainwater and the like from entering. The connecting wire 33 connected to the brush 29 is taken into the glass holder 7 through the hole 25 formed in the glass holder 7. Also in the second embodiment, it is possible to eliminate the waste of providing the liquid crystal sheet 23 up to the peripheral portion of the sunroof glass 3 as in the case of the above-mentioned embodiment, and to accommodate the connector 32 in the glass holder 7. Therefore, the appearance can be improved.

Although the sliding sunroof is shown in this embodiment, the present invention is not limited to the sliding sunroof, and can be applied to a tilt-up sunroof structure, for example. Moreover, the liquid crystal sheet is not limited to being provided on the sunroof glass, and for example, a solar cell or a display body may be provided. Further, it is not limited to the glass panel, and may be a resin or metal sunroof panel.

As described above, according to the present invention, since the lead wire is not taken out from the end surface of the sunroof panel having the structure in which the electric element is sandwiched, the end surface of the sunroof panel can be easily waterproofed and the leads can be easily formed. By providing the wiring extending from the wire to the brush along the stay, the wiring portion can be easily and reliably routed and fixed. Also,
Since it is only necessary to provide the electric element up to the lead-out portion and not the entire surface of the sunroof panel, it is not necessary to wastefully provide the electric element even to the part that covers the peripheral edge of the sunroof panel, and the cost of parts is reduced.
