PROBLEM TO BE SOLVED: To provide a resin exterior trim part for a vehicle which has a simple structure and can advantageously reduce a vehicle exterior noise by advantageously exhibiting a sound absorbing effect in a desired frequency band.SOLUTION: In a resin exterior trim part (10) for a vehicle in which a plurality of through holes (18) are formed on a resin plate-like body (12) at predetermined intervals, flange portions (24), which are integrally raised up from a peripheral edge portion of the through holes (18) by a prescribed height, are formed, and film vibration portions (26), which are vibrated by a sound pressure of a vehicle exterior noise and have thicknesses thinner than the film thickness of the plate-like body (12), are formed on at least a part of the flange portions (24).SELECTED DRAWING: Figure 3

    【課題】構造が簡略であり、且つ所望の周波数帯域における吸音効果が有利に発揮され得ることによって、車外騒音を有利に低減可能な車両用樹脂製外装品を提供すること。【解決手段】樹脂製の板状本体(12)に、複数の貫通孔(18)が互いに所定の間隔を隔てて形成されてなる、車両用樹脂製外装品(10)において、貫通孔(18)の周縁部から一体的に所定高さで立ち上がるフランジ部(24)を形成すると共に、かかるフランジ部(24)の少なくとも一部に、車外騒音の音圧により振動せしめられる、板状本体(12)の板厚よりも薄い厚さの膜振動部(26)を形成した。【選択図】図3
