Abstract

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.
