AIR INTAKE DUCT OF SADDLE-RIDDEN VEHICLE

摘要

Provided is an air intake duct (70) that is of a saddle-ridden vehicle and that can prevent a decrease in supercharger (42) efficiency by suppressing a decrease in the flow rate of intake air (I). The air intake duct (70), which is of a two-wheeled automobile, supplies traveling wind (A) to the supercharger (42) of an engine (E) as intake air (I). The air intake duct (70) has a duct area that gradually diminishes from an anterior air intake opening (24) to a downstream section (70c) connected to the posterior supercharger (42).
