ABSTRACT:
An air inlet pipe 4 connected to an air cleaner 2 of an engine room is extended in such a manner as it surrounds a drain hole 8 arranged at the bottom of air cleaner 2. The body of the air inlet pipe 4 is connected to the air cleaner 2. Since the air inlet pipe 4 surrounds the outside space of the drain hole 8 like a barrier, water or snow entering the engine room cannot reach the drain hole 8. Even if the number of engine rotations and negative pressure are increased, the water and snow are not sucked into drain hole 8 and the suction passage is secured.
