Abstract:
1. A work vehicle having an engine and a belt-type CVT, comprising: a muffler which is configured to flow exhaust from the engine and extends in a transverse direction of a vehicle body so as to allow the exhaust from the engine to flow in the transverse direction of the vehicle body; a CVT case which is configured to cover the belt-type CVT and positioned frontward of the muffler in a longitudinal direction of the vehicle body, the CVT case including a cooling structure configured to introduce cooling air from outside, cool the belt-type CVT, and discharge the cooling air from a discharge part; and an exhaust duct including: an inflow opening to be connected to the discharge part of the CVT case for allowing the cooling air to flow into the exhaust duct; and an exhaust opening for allowing the cooling air to flow out rearward of the vehicle body; wherein the exhaust opening is elongated in an extending direction of the muffler and oriented in a direction that allows the cooling air flowing out to hit the muffler; wherein a cross-sectional horizontal length of the exhaust opening in the extending direction of the muffler is longer than a cross-sectional horizontal length of the inflow opening, and a cross-sectional vertical length of the exhaust opening is shorter than a cross-sectional vertical length of the inflow opening.
