To provide a door weather strip which is excellent in door closing performance corresponding to weight saving of a door.MEANS FOR SOLVING THE PROBLEM: A hollow seal part 12 of a door weather strip 10 has a cross-sectional shape of a substantially parallelogram which is configured from a bottom wall 14, a first peripheral wall 15, a second peripheral wall 16, and a third peripheral wall 17. An angle α between the bottom wall 14 and the first peripheral wall 15 is an obtuse angle. When closing a door 1, the first peripheral wall 15 is moved so that the angle α between the bottom wall 14 and the first peripheral wall 15 becomes small, and the second peripheral wall 16 and the third peripheral wall 17 are interlocked with this, the cross-sectional shape of the hollow seal part 12 is changed from the substantially parallelogram to a substantially rectangular shape, whereby an area of the hollow seal part 12 is increased and an inner pressure thereof is decreased.SELECTED DRAWING: Figure 4
【課題】ドアの軽量化に対応したドア閉まり性能に優れたドアウェザストリップを提供する。【課題を解決するための手段】ドアウェザストリップ10の中空シール部12は、底壁14、第1周壁15、第2周壁16と第3周壁17で構成される略平行四辺形の断面形状を有する。底壁14と第1周壁15のなす角度αは鈍角である。ドア1閉時には、底壁14と第1周壁15のなす角度αが小さくなるように第1周壁15が動き、それに第2周壁16と第3周壁17が連動して中空シール部12の断面形状は、略平行四辺形から略長方形に変化することで中空内部12Bの面積が増加し、内圧が減少する。【選択図】図4
