Description

  The present invention relates to a sunroof structure for a vehicle.

2. Description of the Related Art A so-called sunroof is known in which an opening is formed in a roof portion of a vehicle and daylighting is performed from the opening.
In a general sunroof, a translucent member having translucency is provided in an opening of a roof panel. Since the translucent member is exposed to the outside of the vehicle and directly affected by sunlight and wind and rain, the translucency is maintained by using a relatively durable member such as glass.

Further, a general sunroof is provided with a light-shielding member having a light-shielding property so that the headliner can be opened and closed when the sun is strong, or the light-transmitting member itself has a certain light-shielding property.
For example, a sunroof structure having a configuration in which a polarizing film or the like is provided in a glass translucent member to adjust the translucency continuously is disclosed (see Patent Document 1).
