To provide a door weather strip which can inhibit reduction of a seal pressure applied to a vehicle body panel by a hollow seal part and prevent reduction of seal performance and sound insulation performance.SOLUTION: In a door weather strip, a tip part 23a of a hollow seal part 23 elastically contacts with a vehicle body panel 9 to deflect and thereby seal a gap between a door panel and a vehicle body panel when a front door is closed. The tip part of the hollow seal part has: a projection part 26 which elastically contacts with the vehicle body panel when the door is closed; and a thick seal part 27 which is formed continuously with the projection part and elastically contacts with the vehicle body panel with the projection part. The projection part and the thick seal part are configured so that a direction of the pressure of the seal elastically contacting with the vehicle body panel is parallel to or substantially parallel to a door moving direction when the door is moved in a vehicle outer direction through door glass 11 by a negative pressure during travelling of the vehicle.SELECTED DRAWING: Figure 5

    【課題】中空シール部の車体パネルに対するシール圧の減少化を抑制して、シール性能や遮音性能の低下を防止できるドアウェザーストリップを提供する。【解決手段】フロントドアのドア閉時に、中空シール部23の先端部23aが車体パネル9に弾接して撓み変形することにより、ドアパネルと車体パネルとの間をシールするドアウェザーストリップであって、中空シール部の先端部には、ドア閉時において、車体パネルに弾接する突起部26と、この突起部と連続して形成され、該突起部と共に車体パネルに弾接する肉厚シール部27と、を有し、突起部と肉厚シール部は、ドアが車両の走行中の負圧によってドアガラス11を介して車外方向に移動した際に、車体パネルと弾接したシール圧の方向が前記ドアの移動方向と平行あるいはほぼ平行となるように構成した。【選択図】図5
