A cabin system to be mounted on a vehicle body includes a driver's seat, an air conditioner body for indoor air conditioning disposed downwardly of the drive's seat, a plurality of support pillars constituting a cabin framework, a ceiling portion, and a main duct having a hollow tubular construction, the main duct forming therein an air passageway for the indoor air conditioning. The main duct includes, at a lower portion thereof, a duct connecting opening to be connected to the air conditioner body and also includes, at a lateral portion thereof, a support pillar engaging face. The main duct is attached through the support pillar engaging face to one of the support pillars along an indoor side peripheral face of the one support pillar. The support pillar engaging face of the main duct and the indoor side peripheral face of the one support pillar have profiles complementary with each other.

An engine cooling structure comprises a hood enclosing an engine and defining air inlets and an air outlet, a radiator disposed rearwardly of the engine, a cooling fan disposed forwardly of the engine for drawing cooling air and exhausting the cooling air forwardly. A closed cooling duct system extending from the air inlets to the air outlet is formed by the hood, a guide plate for guiding all incoming air flows to the radiator, and shielding plates extending from a forward body frame and sealing an engine room from below. The cooling air flows through the radiator, past the engine and through the cooling fan.
