<P>PROBLEM TO BE SOLVED: To provide a work vehicle which prevents an increase in temperature of a muffler, by rationally using cooling wind used for cooling a belt continuously-variable transmission. <P>SOLUTION: The work vehicle includes a variable-speed case 64 which accommodates a driving pulley 61, a driven pulley 62, and an endless belt 63 which is wound around the pulleys. The variable-speed case 64 is configured to introduce cooling wind and discharge it from an exhaust duct 68 of a discharge section 64F. The work vehicle includes a horizontally-long muffler 40 whose longitudinal direction is located along a vehicle body horizontal direction, at the back side of the vehicle body. The direction of discharging the cooling wind from the exhaust duct 68 is set so that the cooling wind from the exhaust duct 68 is blown against the muffler 40 from a direction orthogonal to the muffler 40. <P>COPYRIGHT: (C)2012,JPO&INPIT |
