To provide a door weather strip configured so that proper flexural deformation of a hollow seal part can be secured.SOLUTION: In a door weather strip (4) according to the present invention, a hard coating part (64) formed of materials which are harder than an outer periphery side of a hollow seal part (6) is provided at a portion of an inner periphery side of the hollow seal part (6). Therefore, a portion where the hard coating part (64) is provided hardly flexurally-deforms and a portion where the hard coating part (64) is not provided easily flexurally-deforms, when a door (1) is closed, which can control the flexural deformation of the hollow seal part (6) in a proper attitude. Consequently, the proper flexural deformation of the hollow seal part (6) can be secured when the door (1) is closed, which can suppress folded crinkle from occurring when the hollow seal part (6) elastically contacts a vehicle body panel (2), so that good appearance of the door weather strip (4) can be maintained.SELECTED DRAWING: Figure 3

    【課題】中空シール部の適切な撓み変形を確保し得るドアウエザーストリップを提供する。【解決手段】本発明に係るドアウエザーストリップ(4)では、中空シール部(6)の内周側の一部に、当該中空シール部(6)の外周側よりも硬質な材料で形成された硬質被膜部(64)が設けられている。これにより、ドア(1)の閉時において、硬質被膜部(64)が設けられている箇所は撓み変形し難く、硬質被膜部(64)が設けられていない箇所は撓み変形し易くなるため、中空シール部(6)の撓み変形を、適切な姿勢に制御することが可能となる。その結果、ドア(1)の閉時における中空シール部(6)の適切な撓み変形が確保され、中空シール部(6)が車体パネル(2)と弾接した際の折れ皺の発生を抑制し、ドアウエザーストリップ(4)の良好な外観を維持することができる。【選択図】図3
