  • Patent number: 8671787
    Abstract: An output shaft, to which the rotational force of a motor is transmitted, is rotatably supported and housed in a case. One end of the output shaft protrudes from the case, and a pinion gear is provided on this one end. Teeth that mesh with the pinion gear are provided on the outer circumferential surface of cables. A guide member for guiding the cables in such a way that they mesh with the pinion gear is mounted on the case. An urging plate portion that presses against the side of the pinion gear is provided on the guide member. The urging plate portion urges the output shaft in the axial direction and, as a result, rattle of the output shaft is alleviated.

  • Patent number: 8500193
    Abstract: A vehicle roof having at least one cover element, which selectively closes or at least partially exposes a roof opening and which, with respect to a vehicle longitudinal center plane, comprises a carrier element on either side, the carrier element comprising a guide web that interacts with an adjusting device that is guided in a guide rail and comprises a drive carriage, which interacts with the guide web at least to pivot the cover element and comprises a guide element on which the guide web rests. When moving the cover element in the vehicle longitudinal direction, each guide element of the drive carriages serves as a dog element, which engages in a corresponding dog recess configured at the respectively associated carrier element of the cover element.

  • Patent number: 8348240
    Abstract: An output shaft to which the rotational force of a motor is transferred is housed in a case. One end side of the output shaft protrudes from a side surface of the case. A pinion gear is fixed to one end side of the output shaft. Teeth that mesh with the pinion gear are formed on the outer circumferential surface of cables. Cable guide surfaces for guiding the cables to mesh with the pinion gear are provided on the side surface of the case.

  • Patent number: 5902008
    Abstract: A drainage structure for use in a sunroof apparatus is provided including a pair of drain drips (7) respectively attached to one ends of a pair of longitudinally extending opposite guide rails (3) of the sunroof apparatus mounted on a vehicle roof (2), the pair of drain drips (7) each having a drain path portion (9) and a communication path portion (11), the respective communication path portions (11) of the pair of drain drips (7) being interconnected through a communication tube (10) and oriented toward a transversely central side of the vehicle roof (2). With this drainage structure, even when water flows from an upper one of the drain drips (7) to a lower one of the drain drips (7) due to tilting of the vehicle to the right and left, the water is less likely to flow into a lower one of the guide rails (3) and hence is prevented from leaking into the inside of the vehicle.
