Claims (1)
って、その途中に一端閉鎖の消音用分枝管を分岐設置し
たエアクリーナダクトにおいて、上記分枝管はエンジン
回転数に応じてその消音効果域を変更すべく閉鎖端面を
移動可能となして分校管の有効長さを可変としたことを
特徴とするエアクリーナダクト。In an air cleaner duct that introduces outside air into the air cleaner, in which a branch pipe for silencing with one end closed is installed in the middle of the air cleaner duct, the branch pipe is designed to change its silencing effect area according to the engine speed. An air cleaner duct characterized in that the closed end face is movable to make the effective length of the branch pipe variable.
