To provide a weather strip of an automobile door that can improve sound insulation and door closing performance and prevent a cutting residue from occurring.SOLUTION: A weather strip of an automobile door comprises a mounting base part 21 that is mounted on an automobile door 100, and a hollow seal part 22, formed integrally with the mounting base part 21, which elastically contacts a body 200 when the door is closed. The hollow seal part 22 is constituted of an outer hollow wall 22A swelling and curving toward outside of an automobile, an inner hollow wall 22B swelling and curving toward inside of the automobile, a top part hollow wall 22C and a connection hollow wall 22D. An air vent hole H for venting internal air to the outside is arranged in the hollow seal part 22. A sponge layer 30 which is lower in specific gravity than the outer hollow wall 22A, the inner hollow wall 22B, the top part hollow wall 22C and the connection hollow wall 22D is arranged at a site other than a site where the air vent hole H is formed, on an inner peripheral surface of the hollow seal part 22.SELECTED DRAWING: Figure 1
【課題】遮音性及びドア閉じ性を向上させるとともに切りカスの発生を防止する。【解決手段】自動車用ドア100に取付けられる取付基部21と、取付基部21に一体成形されドア閉時にボディ200に弾接する中空シール部22を有し、中空シール部22は、車外側に向けて膨出湾曲した外側中空壁22Aと、車内側に向けて膨出湾曲した内側中空壁22Bと、頂部中空壁22Cと、連結中空壁22Dからなり、中空シール部22に内側の空気を外側に抜くためのエア抜き穴Hが設定されたもので、中空シール部22の内周面に、外側中空壁22A,内側中空壁22B,頂部中空壁22C及び連結中空壁22Dよりも低比重のスポンジ層30を、エア抜き穴Hが設定される部位を外して設定した。【選択図】図1
