In a working vehicle (1), an exhaust gas aftertreatment device is provided in an engine compartment (4) that is adjacent to a cooling fan through which cooling air is supplied to a heat exchanger. The exhaust gas aftertreatment device includes a selective catalytic reduction device in which ammonia obtained from a urea aqueous solution is used as a reduction-causing agent. A urea aqueous solution pipe (47) through which the urea aqueous solution is supplied is laid to the selective catalytic reduction device through the engine compartment (4). In the engine compartment (4), a pipeline-forming member (10) having pipelines (11, 12) in which the urea aqueous solution pipe (47) is installed. The cooling air sucked by a cooling fan flows into the pipelines (11, 12). |
