Abstract: In a vehicle in which an air cleaner is disposed above an engine and connected with the engine through an intake pipe, an air intake passage for guiding air into the air cleaner is provided on the upper surface of a front fender covering a front wheel of the vehicle, so that particulates such as dust or the like entrained in running air is separated from the running air to admit the air free of the particulates into the air cleaner.

Abstract: An exhaust pipe apparatus for a vehicle in which an exhaust pipe for an engine is disposed below an occupant's seat. The apparatus includes an auxiliary exhaust pipe having a bent portion which is bent at a substantially right angle with respect to the axis of the exhaust pipe. The auxiliary exhaust pipe is water-tightly connected to the rear end portion of the exhaust pipe in such a manner that the auxiliary exhaust pipe is pivotable between a reclining position where it is reclined below the seat and an erect position where it is erected above the seat. This arrangement makes it possible to effectively prevent water from entering the exhaust pipe when the vehicle is running through a ford, for example, by pivoting the auxiliary exhaust pipe, which is normally placed at a relatively low position, to the erect position and retaining the auxiliary exhaust pipe in this position.
