With this configuration, the electrical components 68 can be disposed in the dead space formed between the straight line 63 passing through the upper end portion 67a of the meter 67 and the front end portion 58a of the front cowl 40 and the intake duct 60, and the dead space can be effectively used.
Further, since the intake passage 58 is formed by the intake duct 60 and the intake port 51 formed in the front cowl 40, the meter 67 is disposed rearward of the intermediate portion of the longitudinal length of the intake duct 60, and the electrical components 68 are disposed forward of the intermediate portion of the longitudinal length of the intake duct 60, the meter 67 and the electrical components 68 can be disposed in the dead space formed between the intake duct 60 and the straight line 63 passing through the upper end portion of the meter 67 and the front end portion 58a of the front cowl 40, and the dead space can be effectively used.
As shown in fig. 6, the intake duct 60 is a center duct, and is disposed at the center in the vehicle width direction, and the electric components 68 are disposed inside the width W of the intake duct 60.
With this configuration, the vehicle body front portion can be made compact by disposing the electrical component 68 at a position inside the width W of the intake duct 60.
As shown in fig. 6, 7, and 8, a pair of left and right resonators 70 are provided in the intake duct 60. The left and right resonators 70 have duct connection portions 70a as connection portions connected to the left and right side walls 60j of the intake duct 60, respectively, and the left and right resonators 70 extend to positions above the upper surface 60d of the intake duct 60. The electrical components 68 are disposed on the inside of the left and right resonators 70 in the vehicle width direction.
According to this configuration, since the electrical components 68 are disposed within the width W of the intake duct 60, the left and right resonators 70 can be easily disposed by utilizing the space on the outer side of the intake duct 60 in the vehicle width direction.
As shown in fig. 6 and 7, a pair of left and right headlights 52 are provided on the left and right sides of the air intake duct 60, the upper surface 60d of the air intake duct 60 is positioned above the headlights 52, and the left and right resonators 70 are disposed above the headlights 52 (specifically, the housings 94 of the headlights 52).
