PROBLEM TO BE SOLVED: To filtrate suction air of a cooling fan by dust-proof nets and prevent dust from adhering to a radiator when the dust adhering to the dust-proof nets is removed.SOLUTION: A motive part structure of a work vehicle includes multiple endless dust-proof nets (4a, 4b) which revolve around a radiator (2) and a cooling fan (1) so that the dust-proof nets sandwich a shaft center of the cooling fan (1). Further, an intermediate dust-proof body (3) which prevents dust from intruding from a space between the dust-proof nets (4a, 4b) to the radiator (2) side is provided in a gap part between the multiple dust-proof nets (4a, 4b). The intermediate dust-proof body (3) is disposed so that at least a part of the intermediate dust-proof body (3) overlaps with the dust-proof nets (4a, 4b). |
