PROBLEM TO BE SOLVED: To increase joining fusion strength by eliminating fusion peeling and the shortage of joining force of the general part of a door glass run and a corner mold molding part. SOLUTION: With regard to a part for molding a relatively thick bottom wall part 9 and a side wall part 5 on the inner side in a core 19 for molding a corner mold molding part 1C, a gradually changing projection part 20 the height of which is increased gradually from a position by a prescribed distance in front of a position corresponding to the joining faces to a position corresponding to the joining faces is formed. As regards the corner mold molding part 1C, at the position corresponding to the joining faces, in spite of being the bottom wall part 9 and the side wall part 5, they are molded to be converged with a wall thickness equivalent to that of a side wall part 6 on the outer side which is the minimum wall thickness place and a seal lip 4. |
