An air intake duct (70) of a motorcycle forms an air intake passage (77) for supplying an intake air (I) to a supercharger (42). The air intake duct (70) forms a curve portion and is connected to the supercharger (42). The air intake passage (77) has a transverse cross-section which is shaped such that a dimension (D1) in an orthogonal direction that is orthogonal to a radial direction of the curve portion is gradually reduced from the center of the curve portion toward an outer side, in the radial direction, of the curve portion.
