PROBLEM TO BE SOLVED: To easily reduce, at a low cost, noise emitted when an object to be put on a deck hits on a steel plate.SOLUTION: In a deck structure 1 for a dump truck, a rear 2a of a deck 2 opposite a surface 2b for receiving objects M put on it is coated with a resin material 3. The resin material 3 comprises: a primer layer 31 covering the rear 2a of the deck 2 and comprising modified polyurethane primer containing polybutadiene; and a resin coating film 32 covering the surface of the primer layer 31 and having radiation sound resistance that reduces radiation sound caused by vibration of a steel plate.SELECTED DRAWING: Figure 1

    【課題】簡単かつ低コストで、荷台に投入される投入物が鋼板に当たる際に生じる騒音を低減することができる。【解決手段】投入物Mを受ける荷台2の表面2bとは反対側の裏面2aに樹脂材料3が被覆されてなり、樹脂材料3は、荷台2の裏面2aに被覆されポリブタジエン系ゴムを含む変性ポリウレタン系プライマーからなるプライマー層31と、プライマー層31の上に被覆され、鋼板の振動に伴う放射音を低減する耐放射音性を有する樹脂塗膜32と、から構成されたダンプトラックの荷台構造1を提供する。【選択図】図1
