CORNER PIECE MOUNTING STRUCTURE OF AUTOMOBILE DOOR

摘要

PROBLEM TO BE SOLVED: To enhance a vibration-prevention effect in a car width direction by supporting a neighborhood part at an upper apex of an approximate triangle of a corner piece. SOLUTION: A tongue piece accommodation part 21 provided on a back surface of the corner piece 5 and an engagement tongue piece 22 provided on a rear side side part 2R of a door sash 1 are engaged with each other by vertically inserting them. Since the tongue piece accommodation part 21 can be made to a size occupying a relatively small area allowing insertion of the engagement tongue piece 22 compared to an upper end area of the corner piece 25, the tongue piece accommodation part 21 and the engagement tongue piece 22 corresponding thereto can be formed as close as possible to the apex of a sharp angle at the upper end of the corner piece 5. Thereby, a vibration- prevention effect of the upper end of the corner piece 5 can be enhanced.
