ABSTRACT:
A vehicle having moving funnels separated from stationary funnels that suppresses any decrease in intake efficiency. The moving funnels are arranged on an intake side of the stationary funnels to lead air to an engine. A funnel holding section holds the moving funnels and includes opened holes. The moving funnels are moved straight between separated positions in which openings of the moving funnels are separated from openings of the stationary funnels, and abutment positions in which the openings of the moving funnels abut against the openings of the stationary funnels. The opened holes pass air on an upstream side to a downstream side.
