PROBLEM TO BE SOLVED: To absorb a sound wave generated in an engine room, and to also relieve impact added to a pedestrian when colliding with the pedestrian.SOLUTION: At least a part of an automobile hood as an automobile exterior article is constituted of a resin honeycomb structure. The honeycomb structure comprises a honeycomb part composed of a plurality of cells 24 mutually partitioned by a partition wall 14 and forming a cylindrical shape by extending in the inner-outer directions, an inner plate part 31 arranged inside the honeycomb part and an outer plate part 32 arranged outside the honeycomb part and sealing the respective cells 24 by sandwiching the honeycomb part from both inner-outer sides together with the inner plate part 31. The respective partition walls 14 are provided with a communication hole 18 for communicating an engine room 10 with an inside space of the cells 24, and are also provided with an absorption part (a connection plate part 17) for absorbing energy by being deformed on the periphery of the communication hole 18 when external force is added toward the inside via the outer plate part 32.

    【課題】エンジンルームで発生する音波を吸収するとともに、歩行者との衝突時には歩行者に加わる衝撃を緩和する。【解決手段】自動車用外装品としての自動車用フードの少なくとも一部は、樹脂製のハニカム構造体によって構成されている。ハニカム構造体は、隔壁14により互いに区画され、かつ内外方向へ延びて筒状をなす複数のセル24からなるハニカム部と、ハニカム部の内側に配置される内板部31と、ハニカム部の外側に配置されて、内板部31とともにハニカム部を内外両側から挟み込んで各セル24を封止する外板部32とを備える。各隔壁14には、エンジンルーム10とセル24の内部空間とを連通させる連通孔18を有し、かつ外板部32を通じて内側へ向かう外力が加わった場合に連通孔18の周辺で変形してエネルギーを吸収する吸収部(連結板部17)が設けられている。【選択図】図3
