PURPOSE:To improve rigidity of a door sash, by mounting a door weather strip in the periphery of an inner sash with a retainer, jointing a side wall to a rise- up wall of the inner sash, forming the side wall to the retainer and constituting a closed sectional part in a joint between said both walls. CONSTITUTION:A door is constituted in such a manner that a side wall 5a is formed to a retainer 5, for mounting a door weather strip 6 jointed to the periphery of an inner sash 4 of a door sash 2, and this side wall 5a is jointed to a rise-up wall 4a of the sash 4. Here a closed sectional part 10 is formed between the side wall 5a and the rise-up wall 4a, and this closed sectional part 10 is formed by bead parts 11, 12 provided respectively to the side wall 5a and the rise-up wall 4a. While the bead part 11 in a side of the side wall 5a is formed to be capable of holding the door weather strip 6. In this way, the closed sectional part 10 serves as a framework strength member, then bending rigidity and torsional rigidity can be improved. |
