いた。Problems to be Solved by the Invention In the conventional radiator grill device, as shown in FIG. 9, the sound-absorbing louvers are horizontally shaped with a slight inclination and are fixedly attached. Therefore, since the interval D between the sound absorbing louvers is constant, the area of the cooling air outlet is limited. As a result, when a construction vehicle performs work such as traveling with an unbalanced load, its heat balance deteriorates. Furthermore, when construction vehicles operate in urban areas, even if attempts are made to reduce engine noise, it is not possible to reduce the spacing between the sound-absorbing louvers, resulting in noise pollution.
