きる。[Effects of the Invention] As explained above, according to the present invention, an air conditioning system is configured that includes a path in which cold air or hot air circulates along the inner surface of the cabin, and paths in which the air flows in front of and behind the driver. Since the air conditioning system and seats necessary for this are installed in the cabin, the driver can properly operate this air conditioning system to achieve the desired state, which changes depending on the operating region, season, solar radiation, and other environmental conditions. The cabin temperature and the surface temperature of each part of the driver's body can be maintained at a comfortable level throughout the year. This significantly reduces the physical and mental load on the driver, and improves work efficiency. Furthermore, since there are no air conditioners, air outlets, etc. installed in front of the seats, sufficient forward visibility can be ensured.
