Abstract
【解決手段】表側パネル17のパネル本体21表裏面に樹脂密度が高くて堅い薄肉のソリッド層25を形成するとともに、パネル本体21内部に、ソリッド層25に挟まれ内部に多数の空隙を有し、ソリッド層25よりも樹脂密度が低い発泡層27を形成する。また、裏側パネル19裏面に振動溶着時における振動方向に延びるようにソリッドからなる溶着リブ41を一体に突設する。溶着リブ41先端部を表側パネル17のパネル本体21裏面のソリッド層25を突き破って発泡層27に侵入させて発泡層27及び裏面側ソリッド層25と溶着一体化する。

Description
図1は、自動車1の後部荷室3を示す斜視図であり、図2は図1のA−A線における断面図である。
図6は、本発明の実施形態2に係るフロアボード5を示す。この実施形態2では、裏側パネル19のパネル本体33の溶着リブ41突設箇所に、パネル本体33の表裏面に形成されたソリッド層37よりも厚肉のソリッドからなるベース層49が、パネル本体33表裏面のソリッド層37を一体に連結するように表裏面に亘って形成され、該ベース層49には発泡層39が形成されていない。該ベース層49の厚さは、パネル本体33の厚さの略1/2に設定され、ベース層49の表側(図6の下側)は、ベース層49周囲のパネル本体33表側ソリッド層37と面一になっており、ベース層49の裏側(図6の上側、すなわち表側パネル17側)に凹条部47が溶着リブ41に沿って形成されている。上記ベース層49、すなわち上記凹条部47の底面には、上記溶着リブ41及び補強リブ43が一体に突設されている。
