PROBLEM TO BE SOLVED: To provide a vehicle interior material having a dimming function which can switch a shield state for shielding light, and a dimming state for allowing the passage of a constant quantity of light, and obtaining a glare-proof effect.SOLUTION: An interior material for a vehicle having a dimming function comprises; the plate-shaped vehicle interior material having an opening part 22; a fixed polarizer 30 and a movable polarizer 40 which are in states that two band-shaped polarization films 34X, 34Y and 44X, 44Y which are different from each other in polarization directions in a position covering the opening part 22 are alternately aligned in row shapes at constant intervals; and a mesh material 28 which covers a face of the inside of the vehicle. The fixed polarizer 30 and the movable polarizer 40 are arranged in an air space S in which polarization film layers 34, 44 oppose each other, and do not closely contact with each other, and the movable polarizer 40 is movable toward an alignment direction of the band-shaped polarization films 34X, 34Y at the fixed polarizer 30, thus making a shielding state and a dimming state which are switchable with respect to each other.SELECTED DRAWING: Figure 4

    【課題】光を遮る遮光状態と、一定量の光の通過を可能にして防眩効果を得る調光状態と、が切換可能な調光機能付き乗物用内装材とする。【解決手段】開口部22を有する板状の乗物用内装材と、開口部22を覆う位置において偏光方向の異なる2つの帯状の偏光膜34X,34Y及び44X、44Yを交互に且つ列状に一定間隔で配列された状態の固定偏光板30及び可動偏光板40と、乗物の内方側の面を覆うメッシュ材28と、を備え、固定偏光板30及び可動偏光板40は、互いの偏光膜層34、44が向かい合うように且つ密着しない空隙Sで配設されており、固定偏光板30における帯状の偏光膜34X、34Yの配列方向に向かって可動偏光板40が可動して、遮光状態と、調光状態と、に切換可能に構成される。【選択図】図4
