<p>PROBLEM TO BE SOLVED: To prevent the invasion of the sound from under a rear sheet by making the laying range of a floor carpet cover from a general plane of a floor panel exposed outside to a shielding plane under a rear sheet and also reach a boundary wall between a crew cabin and a load room. SOLUTION: Between an engine room and a crew cabin, and the crew cabin and a load room are partitioned by panels 15a, 15b, respectively, and a floor carpet 30 is laid on a floor panel 15 of the crew cabin to serve the role of decoration and soundproofing. And the range where the floor carpet 30 is laid is such that it covers from a lower end of the boundary panel 15a to the engine room, through a general plane 16 and a shielding plane 17 made higher for the installation of a rear sheet, to the boundary panel 15b to the load room. The laying range of the floor carpet 30 is extended to the shielding plane under the rear sheet in this way so that the invasion of the outside noise from this part is reduced.</p> |
