PROBLEM TO BE SOLVED: To obtain stable sealability at a mold formation part.SOLUTION: A mold formation method of a weather strip 30 for an automobile comprises: a fitting base 31B which is fitted in a fitting member 5 provided along a body opening edge of a sashless door type vehicle; and a hollow seal part 32B which is integrally provided with the fitting base 31B, and elastically contacts side glass 4 when a door is closed, and is provided with a bridge 35B for bisecting a hollow area is provided inside the hollow seal part, in which a slit 37B which penetrates from an inner surface to an outer surface, and extends in a longitudinal direction is formed at the fitting base 31B, and mold formation of the bridge 35B between two set corrugating media of which a mold formation material is filled to bisect the hollow area is integrally performed with the hollow seal part 32B so that one end 35B1 of which is connected with an inner surface side of a seal wall of the hollow seal part 32B, and the other end 35B2 is inserted into a slit 37B of the fitting base 31B at a position to be inside of the hollow seal part 32B, and after that, the corrugating media are extracted outward from the slit 37B.SELECTED DRAWING: Figure 1
【課題】型成形部において安定したシール性を得ること。【解決手段】サッシュレスドア型車の車体開口縁に沿って設けられた嵌合部材5に嵌め込まれる取付基部31Bと、取付基部31Bに一体的に設けられドア閉時にサイドガラス4に弾接する中空シール部32Bを備え、中空シール部の内部に中空領域を2分割するブリッジ35Bが設けられた自動車用ウェザーストリップ30の型成形方法で、取付基部31Bに内面から外面にかけて貫通し長手方向に延びるスリット37Bを形成し、中空シール部32Bの内部になる位置に、セットされた2つの中芯間に型成形材料が充填されて中空領域を2分割するブリッジ35Bを、その一端35B1が中空シール部32Bのシール壁の内面側に接続され、他端35B2は取付基部31Bのスリット37B内に挿入されるように、中空シール部32Bと一体的に型成形した後、中芯をスリット37Bから外方に抜き出すようにした。【選択図】図1
