る。(Problems to be Solved by the Invention) In the above-mentioned conventional rough terrain vehicle, heavy objects such as the fuel tank and the mission case are distributed to the left and right, but the fuel tank is arranged on one side behind the engine. Therefore, the air cleaner case must be disposed in the rear space of the engine, and as a result, the air cleaner case and the exhaust pipe are brought close to each other, and the air cleaner case is thermally adversely affected.
また、エアクリーナケースをエンジン後方に配置したこ
とにより、このエアクリーナとキャブレターとを接続す

り、エンジン後方にチューブ類が密集し、エンジン冷却
風の通気性も悪化する。Also, by arranging the air cleaner case on the rear side of the engine, it will be arranged on the rear side of the connecting engine that connects the air cleaner and the carburetor, and the tubes are densely packed on the rear side of the engine, and the ventilation of the engine cooling air is deteriorated. .
更に燃料タンクとエアクリーナケースとが車体の巾方向
に並列に配置されているため、燃料タンク及びエアクリ
ーナケース双方の容量も制限される。Further, since the fuel tank and the air cleaner case are arranged in parallel in the width direction of the vehicle body, the capacity of both the fuel tank and the air cleaner case is limited.
