〔Effect of the invention〕

As described above, the sunshade structure for an automobile according to the present invention has a sunshade moving means that moves the sunshade forward and backward, and when the glass panel is tilted in the opening direction of the roof opening, the sunshade moving means is interlocked with each other. The structure also includes interlocking means for moving the sunshade in the opening direction of the roof opening.

Thereby, when the glass panel is tilted, the sunshade is automatically opened to ensure the required ventilation capacity. In addition, since the sunshade is opened to ensure ventilation capacity, there is no need to provide a ventilation louver on the sunshade, making it possible to improve the appearance of the sunshade from the inside of the vehicle. The cooling and heating effects can be enhanced by the glass panel, the sunshade, and the air layer sealed between them.

Further, when the glass panel is open, the sunshade is always open, so forgetting to close the glass panel is naturally eliminated, and rainwater infiltration into the car and theft of the car are prevented.

Furthermore, since the opening operation of the sunshade is automatically performed by the interlocking means in conjunction with the opening operation of the glass panel, the operability of the sunroof mechanism is greatly improved.
