Description

  The present invention relates to a vehicle sunshade structure. More specifically, the present invention can accurately arrange the left and right rails in parallel, and does not require a dedicated bridging member for increasing the degree of parallelism. It relates to a sunshade structure.

  There has been provided a vehicle having a sunroof-type ceiling for taking sunlight into a passenger compartment. For example, a sunroof having an opening provided on the ceiling of a vehicle, a glass roof for preventing intrusion of wind and rain, and a sunshade for shielding sunlight as necessary is known. In addition, in order to facilitate the opening and closing of the sunshade, it is essential that the rails supporting the sunshade on both sides have a high degree of parallelism, and in order to increase this parallelism, the left and right rails are front-mounted at each front end. There is known a sunshade that is fixed by a rail and that is further bridged around an intermediate portion in the length direction (for example, see Patent Document 1).

  Further known is a vehicle roof comprising an opening formed in a fixed roof panel and two transparent lids arranged side by side to close and at least partially open the opening. (For example, refer to Patent Document 2). In this vehicle roof, a sunshade unit is supported by each lid, and this sunshade unit is movable with each lid.
