The conductor member 42 has a function of grounding static electricity collected on the iron plate members 31 and 32 by the frictional action of the plurality of sunshade panels 21, 22, and 23 to the guide rail 15 via the brush portion 43 and removing the static electricity. The conductor member 42 can be attached to the iron plate members 31 and 32 by the double-sided tape 44, or can be attached by riveting or the like.

  In addition, since the second and third sunshade panels 22 and 23 are substantially in contact with the first sunshade panel 21, the iron plate members 33 to 36 attached to the second and third sunshade panels 22 and 23 include The conductor member 41 is not attached, and these iron plate members 33 to 36 are insulated by an insulating tape or the like.

  Next, the operation of the sunroof device 10 in the above-described embodiment will be described. When the occupant opens the operation switch while the sunshade panels 21, 22, and 23 are closed, the electric motor (not shown) is driven, and the first sunshade panel 21 is connected to the upper guide groove of the guide rail 15 via the wire. It is moved (retracted) toward the rear of the vehicle 5 while being guided by 15a. When the first sunshade panel 21 is retracted to a predetermined position, the rear end portion 21a of the first sunshade panel 21 comes into contact with the flange portion 22a of the second sunshade panel 22, and thereafter, the second sunshade panel 22 is in the first position. In conjunction with the sunshade panel 21, the guide rail 15 is retracted integrally while being guided by the middle guide groove 15b. Further, when the first and second sunshade panels 21 and 22 are retracted to a predetermined position, the flange portion 22a of the second sunshade panel 22 abuts on the flange portion 23a of the third sunshade panel 23, so that the third sunshade panel 23 is integrally retracted while being guided by the lower guide groove 15 c of the guide rail 15 in conjunction with the first and second sunshade panels 22. Thus, when the sunshade panels 21, 22, and 23 are opened to the predetermined positions, the electric motor is stopped.

  Conversely, when the occupant closes the operation switch while the sunshade panels 21, 22, and 23 are open, the electric motor (not shown) is driven in the opposite direction to the first sunshade panel 21 via the wire.

Further, when the first and second sunshade panels 21 and 22 are advanced to a predetermined position, the third contact portion 39 of the second sunshade panel 22 contacts the fourth contact portion 40 of the third sunshade panel 23. Therefore, the third sunshade panel 23 is retracted integrally in conjunction with the first and second sunshade panels 22. Thus, when the sunshade panels 21, 22, and 23 are closed, the electric motor is stopped.

  Due to the relative movement of the plurality of sunshade panels 21, 22, and 23, the sunshade panels rub against each other to generate static electricity, and the static electricity collects on the iron plate members 31 and 32 due to a potential difference. The iron plate members 31 and 32 are conductive members. Since the aluminum guide rail 15 is always in contact via the brush portion 43 of 41, static electricity collected on the iron plate members 31 and 32 is grounded to the guide rail 15 successively, and excessive static electricity is applied to the iron plate members 31 and 32. There is no accumulation. Accordingly, the static electricity accumulated in the iron plate members 31 and 32 is not discharged from the iron plate members 31 and 32 to the guide member 15 all at once, and the passenger is not discomforted by the influence of the static electricity.
