Therefore, in the vehicle side view (right side view), the case portion 212a and the detection unit 212b of the wheel speed sensor 212 are hidden by the bottom case 296 and viewed from outside I will not. For this reason, it can prevent that the wheel speed sensor 212 stands out, and the appearance is good. Further, the sensor bracket 213 provided on the inner side surface 296 a of the bottom case 296 is relatively small, and the whole thereof is hidden in the bottom case 296 in a side view of the vehicle. Therefore, the sensor bracket 213 can be prevented from being conspicuous.
  • the cable 212 d of the wheel speed sensor 212 may be routed from the inner side 296 a to the outside of the bottom case 296 through the opening 303.
  • the brake caliper support portion 298 includes a lower arm portion 299 and an upper arm portion extending in two to support the upper end portion 58a and the lower end portion 58b of the brake caliper 58.
  • a wheel speed sensor mounting portion 220 is provided at the connecting portion 301.
  • the connecting portion 301 connects the lower arm portion 299 and the upper arm portion 300 together.
  • the brake caliper support portion 298 can be reinforced by the joint portion 301, and the wheel speed sensor attachment portion 220 can be provided at a position where the wheel speed sensor 212 is less noticeable using the joint portion 301.
  • the bottom case 296 includes a cylindrical portion 297d to which the lower end of the tube main body 95 of the front fork 224 is coupled, and an adjusting cylindrical portion 305 provided with the adjustment mechanism 307 of the damping force of the front fork 224.
  • the speed sensor mounting portion 220 may be provided in the sensor recess 221 between the cylindrical portion 297 d and the adjustment cylindrical portion 305.
  • the wheel speed sensor 212 can be disposed in the sensor recess 221 to protect the wheel speed sensor 212 and hide the wheel speed sensor 212 in the sensor recess 221. Further, the wheel speed sensor 212 can be compactly arranged in the vehicle width direction.
