摘要 A work vehicle capable of cooling an engine compartment in a simple structure is provided. A partition wall partitions an internal space of an exterior cover into an engine compartment housing the engine and a cooling compartment housing the air blower. The partition wall includes a first wall portion extending at a relatively large inclination with respect to a direction in which an upper side plate of the exterior cover located on the cooling compartment side with respect to the partition wall extends, and a second wall portion extending at a relatively small inclination. An upper opening portion as an air intake port connecting an external space and the internal space of the exterior cover is provided in the upper side plate so as to be located to face the second wall portion. The first wall portion is provided with an opening connecting the engine compartment and the cooling compartment.
