A cooling air introduction pipe 5 having a trumpet shape and opening toward the traveling direction is provided between the vehicle and the vehicle. One end of the cooling air introduction pipe 5, that is, the cooling air introduction port, is fixed to the stay 6 of the front number plate 7 with bolts or the like, and forms an opening 5a.
A porous (mesh-like) front license plate 7 is attached to the. Cooling air introduction pipe 5
The other end, that is, the cooling air outlet, loosely fits into one end of a cylindrical duct 8 made of a flexible member, and the other end of the cylindrical duct 8 is attached so as to open at the front part of the engine cylinder 9. Attachment portions are provided on the surface of the cylindrical duct 8 to fix the cylindrical duct 8, and the cylindrical duct 8 is attached to the vehicle body frame 1 or the like with bolts or the like. The other end of the cooling air introduction pipe 5 is connected to a cylindrical duct 8 near a head pipe 10. The cylindrical duct 8 is separated to the left and right with respect to the center of the vehicle body frame 1 at the connection part with the cooling air introduction pipe 5, and is formed so as to join near the opening in the front part of the engine cylinder 9.

Since there is nothing to prevent this, cooling air can be introduced efficiently.
Further, at least the portion of the cylindrical duct connected to the cooling air introduction pipe is made flexible so that the cooling air introduction pipe can move in accordance with the operation of the handle. Note that it is also possible to form the entire cylindrical duct from a flexible member such as synthetic resin.
