る。 In the various types of movable roofs mentioned above, it is desirable that the ceiling of the cabin be as smooth as possible. but,
When installing a wind deflector in a rotatable manner at the front edge of a fixed roof opening, such as the chevron-shaped sliding roof and ventilating flap type roof mentioned above, the wind deflector can be installed without impairing the smoothness of the ceiling. It is extremely difficult to store. Another important issue in this type of movable roof structure is how to effectively install the sealing material. If the movable roof that engages the roof opening is made of relatively thin, transparent, e.g. single layer synthetic glass, the sealing material may be attached to the movable roof using a metal frame or attached to the perimeter of the movable roof. must be fixed.
However, in the former case, a metal frame for mounting must be prepared separately, which is expensive. In the latter case, the pressed sealing material will protrude from the periphery of the movable roof, making it impossible to satisfy the requirement of smoothing the outer surface of the automobile.
