報に開示されている。2. Description of the Related Art Conventionally, as an outside air intake structure for air conditioning of a vehicle, a traveling wind is introduced into an outside air intake formed in a cowl box serving as a windshield mounting portion, and is taken into an air conditioning unit. There was a method. However, in recent years, there has been a demand for securing as large a living space as possible in the passenger compartment, and thus the passenger compartment length has tended to be gradually widened. Within the prescribed vehicle length range, the length of the engine compartment has been increased by the length of the passenger compartment. As the length of the engine room is shortened, there is a problem that maintenance of the engine such as inspection, repair, and detachment is deteriorated. This occurs because the engine interferes with the cowl box, especially when the engine is detached. Therefore, the traveling wind introduction path having the outside air intake is integrated with the bonnet, and the traveling wind introduction path is moved upward together with the bonnet when the hood is opened, so that the maintainability of the engine is not impaired even in a short engine room. An outside air intake structure for air conditioning is disclosed in JP-A-61-282114.

However, there is a problem that air enters the air conditioning unit together with air. In addition, since the traveling wind introduction path is provided so as to face the engine room, when the air conditioning unit is operated, air is sucked from the drain hole and air in the engine room is also sucked. There is a problem that air in the vehicle interior is polluted.
