Abstract
To provide a noise absorption blade mounting structure for a working vehicle, which is enabled to be excellent in the draft straightening property in an air hole of the cover of an engine room and excellent in the strength and appearance of the cover, by making noise absorption blades having a high noise absorption effect of a simple structure to mount/demount the noise absorption blades simply in/from the air hole thereby to facilitate the tuning against the noises coming from the engine room and the maintenances of the noise absorption blades.Each of the noise absorption blades 8 includes: a core member 14; noise absorption members 15 mounted on the two faces of the core member 14; and mounting members 11, 12 formed on the end faces of the noise absorption members 15. The cover 6 includes in its air hole 6a straightening members 6e for straightening the draft in front of, as taken in the ventilation direction, the noise absorption blades 8.
