1. A work vehicle comprising:
a vehicle body;
an engine hood that is installed in a rear portion of the vehicle body;
a diesel engine that is provided in the engine hood;
a cooling fan that is located in the engine hood at a position forward of the diesel engine;
an emission gas purification device that is provided rearward of the diesel engine in the engine hood, the emission gas purification device being configured to collect particulate matter contained in an emission gas from the diesel engine;
an exhaust flow path extending through an exhaust manifold of the diesel engine to the emission gas purification device along a lateral side surface of the diesel engine;
a cooling air guiding path that is provided in the engine hood, the cooling air guiding path being configured to guide a portion of cooling air from the cooling fan to a heat radiation area to which heat is radiated in a vicinity of a position at which the exhaust flow path and the emission gas purification device are connected with each other;
an air guide that is provided in and separate from the engine hood for guiding the cooling air; and
an in-hood element that is provided in the engine hood, at a position upstream of the heat radiation area in a direction in which the cooling air is sent,
wherein the cooling air guiding path is constituted by a gap between the air guide and the in-hood element,
wherein the in-hood element is in a form of the lateral side surface of the diesel engine which lateral side surface faces the exhaust manifold disposed upstream of the heat radiation area in the direction in which the cooling air is sent,
wherein the air guide has a lateral guide surface facing the lateral side surface and gradually closer to the lateral side surface toward a downstream side in the direction in which the cooling air is sent, and
wherein the gap has a rearwardly narrowed shape that is gradually narrowed toward the downstream side in the direction in which the cooling air is sent.
