In a working vehicle 141, a clogging of an exhaust gas purification device 50 can be cleared without forcedly renewing the exhaust gas purification device 50 during various works while traveling at a low speed. In the working vehicle 141 provided with an engine 70 which is mounted to a travel machine body 142, a common rail type fuel injection device 117 which injects fuel to the engine 70, a continuously variable transmission 159 which shifts power from the engine 70, and the exhaust gas purification device 50 which is arranged in an exhaust system of the engine 70, in the case that an engine operating point Q relating to a rotating speed N and a torque T of the engine 70 is in a low-speed and low-torque side incapable of self-renewing the exhaust gas purification device 50, the engine operating point Q is changed to a high-speed and low-torque side capable of self-renewing the exhaust gas purification device 50, and a change gear ratio of the continuously variable transmission 159 is changed and regulated in such a manner that a vehicle speed V of the travel machine body 142 is not changed.
