Abstract: There are provided a protective film for a polarizing plate, wherein the protective film comprises a stretched film comprising a (meth)acryl-based resin and having an absolute value of a planar orientation coefficient ?P of less than or equal to 2.5×10?4, and a polarizing plate comprising a polarizing film, and the protective film for a polarizing plate laminated on at least one surface of the polarizing film via an adhesive layer. The stretched film can be, for example, a biaxially stretched film.

Abstract: A ventilating device for a roof opening of the type having a cover mounted for closing the roof opening, a cable drive arrangement for displacing the cover from a position closing the roof opening to positions for opening the roof opening by sliding movement and for opening the roof opening by tilting movement, and a sunshade panel displaceable mounted for opening and closing a roof frame aperture located below the roof opening. At least a portion of the sunshade panel is automatically displaced to a position partially opening the aperture when the cover is shifted to a tilted-up position via drive cables of the cover cable drive. The sunshade panel is also displaceable to positions opening the aperture independent of the cover position.
