An air intake apparatus configured to combine air filtered separately through a plurality of air cleaners and lead it to a single throttle body suppresses or prevents variation in the pressure of airflow introduced from a plurality of intake paths to the single throttle body. Outside air is introduced to the plurality of air cleaners by a single air cleaner inlet. The air cleaner inlet has a chamber of a predetermined capacity which has a single intake duct, and a plurality of branching passages which branch off from the chamber into the same number as there are air cleaners and are connected to the separate air cleaners.
