To provide an interior material for a vehicle which is easily sewn while securing rigidity.SOLUTION: When Shore hardness of an interior material for a vehicle is represented by H [Hs], thickness thereof is represented by d [mm], and flexural rigidity thereof is represented by K[Mpa mm4], an index X=H×K×d2 is set to be smaller than an upper limit value that is set according to sewing easiness required for the interior material for the vehicle. Otherwise, the index X is set to be larger than 3,500 and smaller than 54,000.SELECTED DRAWING: Figure 3
【課題】車両用内装材を、剛性を確保しつつ、縫製しやすいものとする。【解決手段】車両用内装材の、ショア硬度をH[Hs]、厚さをd[mm]、曲げ剛性をK[Mpa・mm4]とするとき、指標X=H×K×d2が、車両用内装材に要求される縫製しやすさに応じて設定された上限値より小さくなるようにする。あるいは、指標Xが、3500より大きく、54000より小さいものとする。【選択図】図3
