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。
S1が形成されている。上記表側パネル17のパネル本体21は、表裏面に形成された樹脂密度が高くて堅い薄肉のソリッド層25と、該ソリッド層25に挟まれ内部に多数の空隙を有し、該ソリッド層25よりも樹脂密度が低い発泡層27とを備えている。また、パネル本体21の周縁部21aは、上記ソリッド層25より厚肉のソリッド層から構成され、上記周壁部23も、上記ソリッド層25より厚肉のソリッド層のみから構成されている。また、表側パネル17のパネル本体21及び周壁部23の表面には、見栄えを良くする等の観点から不織布等からなる表皮29が一体に被着されているとともに、車体後方側縁近傍の車幅方向中央には把持用の凹部31(図3に示す)が形成されている。なお、振動溶着時における振動方向を図3に矢印Xで示す。
の表皮29端末に、振動溶着時における裏側パネル19の周壁部35との摩擦によって糸くずやバリが生じることが防止され、見栄えが悪化しない。
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。
パッケージトレイやグローブボックスのリッド等の他の自動車用樹脂成形品、さらには自動車以外の樹脂成形品にも適用することができるものである。
