Description

  The present invention relates to a vehicle door sash, and more particularly to a vehicle door sash made of a roll-formed product of an iron-based material for fixing a weather strip with a clip.

  A weather strip that is compressed between the vehicle door and the door opening of the vehicle body when the vehicle door is closed is fixed to the vehicle door sash. As a weather strip fixing structure, there is known a structure in which clips arranged at appropriate intervals in the extending direction of the weather strip are inserted and fixed to a door sash. The clip fixing type has an advantage that the cross-sectional shape of the sash can be simplified because it is not necessary to form a groove shape for holding the weather strip in the sash itself.

Such a clip-fixing type vehicle door sash is a roll forming having a design portion on the outside of the vehicle in order to escape (accommodate) the clip inserted from the weatherstrip side and form a closed space that prevents interference with the window glass. A part and a roll-formed part having a bag-like portion inside the vehicle are joined by welding or hemming.
