Abstract

A work vehicle includes an engine and a belt-type continuously variable transmission device provided on a lateral side of the engine and configured to (i) receive power from the engine and (ii) output the power to a traveling device while varying the power in terms of speed. The belt-type continuously variable transmission device has (i) an intake port which is present in the transmission device case and through which cooling air is sucked from outside the transmission device case into the transmission device case as a result of rotation of the rotary fan and (ii) a first exhaust port which is present in the transmission device case and through which the cooling air is discharged from inside the transmission device case as a result of the rotation of the rotary fan. The first exhaust port is present on a side of the exhaust pipe on which side the engine is present, and faces the engine.
