PROBLEM TO BE SOLVED: To solve a problem in which cooling efficiency is deteriorated due to providing of a transmission for a fan for cooling within a blowing range of the fan.SOLUTION: This working vehicle includes a continuously variable transmission 11 for traveling for driving a travel device 2 by continuously shifting driving rotation of an engine 10. The fan 20 for cooling, a radiator 21 and a dustproof net 37 are provided outside the engine 10. The fan 20 is driven to normally rotate and reverse by a continuously variable transmission 30 for a fan. In the continuously variable transmission 30, the driving rotation of the engine 10 is inputted via a pump input shaft 14 for traveling of the continuously variable transmission 11.COPYRIGHT: (C)2013,JPO&INPIT【課題】冷却用ファンの送風範囲内にファン用の変速装置が設けられることによる冷却効率の悪化。【解決手段】エンジン10の駆動回転を無段階に変速して走行装置2を駆動する走行用無段変速装置11を備え、前記エンジン10の外側には、冷却用ファン20と、ラジエータ21と、防塵ネット37とを設け、前記冷却用ファン20はファン用無段変速装置30により正転および逆転駆動される構成とし、前記ファン用無段変速装置30には、前記走行用無段変速装置11の走行用ポンプ入力軸14を介してエンジン10の駆動回転を入力する構成としたことを特徴とする作業車輌。【選択図】図3
