To provide a door seal material for a vehicle which maintains high sealability, and has good door closing properties to be capable of surely closing a door even with small force (energy) as compared to a conventional material.SOLUTION: A door seal material 1 for a vehicle mainly includes a seal base part 2 which is fixed to a door and has substantially a flat plate shape, and a seal part 3 which is formed integrally with the seal base part 2 and has a hollow cross section, in which in order to constitute the seal base part 2 and the seal part 3, a first component containing ethylene-propylene-diene rubber and a second component containing carbon black are used as raw materials, and a value obtained by dividing the number of compounding parts of the first component by the number of compounding parts of the second part is within a range of 0.60-2.00. Furthermore, a value of a loss tangent indicating dynamic viscoelasticity may be within a range of 0.095-0.210.SELECTED DRAWING: Figure 1

    【課題】高いシール性の維持とともに、従来と比較して小さな力(エネルギー)であってもドアを確実に閉めることの可能な良好なドア閉まり性を備えた車両用ドアシール材の提供を課題とする。【解決手段】車両用ドアシール材1は、ドア等に固定される略平板状のシール基部2と、シール基部2と一体的に形成された断面中空状のシール部3とを主に具備して構成されるものであり、シール基部2及びシール部3を構成するために、エチレン・プロピレン・ジエンゴムを含む第一成分、及び、カーボンブラックを含む第二成分を原材料とするものであり、第一成分の配合部数を第二成分の配合部数で除した値が、0.60〜2.00の範囲のものである。更に、動的粘弾性を示す損失正接の値が、0.095〜0.210の範囲であってもよい。【選択図】図1
