Abstract: A wheel loader includes an engine, an engine compartment, an injection device, a top plate and a first guide member. The injection device is disposed in the engine compartment. The top plate has a ventilation part. The ventilation part is disposed in a position horizontally away from the injection device. The first guide member has a guide body. The guide body is disposed along the top plate to direct air existing over the injection device to the ventilation part.

Abstract: An engine compartment accommodates an engine. A cooling device is configured to cool the engine. A cooling compartment accommodates the cooling device. A division wall is disposed between the engine compartment and the cooling compartment. A ventilation portion includes a hole for permitting air to pass therethrough and is provided on a top surface of the engine compartment. A water receiving member is disposed under the ventilation portion within the engine compartment. A water catchment member is disposed in the cooling compartment and catches water received by the water receiving member. A drainage pathway is connected to the water catchment member and leads the water to a predetermined drainage position.
