PURPOSE:To promote the reduction of running resistance and the improvement of ventilating efficiency in an engine room, by providing a car room and the engine room to be arranged longitudinally in the central part of a car body whose sectional shape is formed in a wing section, and respectively forming a suction port in a front part or the like of the engine room further a draft port in the rear part of the engine room. CONSTITUTION:A car body 1 is formed its cross section in a wing section by an upper plate 2, bottom plate 3, etc., while setting front edge part 5 low and rear part 6 high. And a car room frame 8 coats its upper part with a front shield glass 2a and a canopy 2b, forming a car room 7. While a rear part of the canopy 2b is separated by a partition B from the car room 7, forming an engine room 15. Here the engine room 15 communicates with the atmosphere respectively through each suction port 16 or the like, opened respectively to the upper plate 2 and a side plate 3, and a slim draft port 18a extending over the whole surface in a car width direction in the rear surface of the car body 1. In this way, the engine room 15, in which a stream of air is induced from each suction port 16 or the like toward the draft port 18a in accordance with running of a vehicle, promotes the ventilation.
