- the wheel 2A is formed of a material having higher thermal conductivity than the front wheel brake disc 36A and the vehicle speed sensor rotor plate 34B. That is, the front wheel brake disc 36A and the vehicle speed sensor rotor plate 34B are connected via the wheel 2A having a higher thermal conductivity.
- the front wheel brake disc 36A and the vehicle speed sensor rotor plate 34B are directly fixed to the wheel 2A or fixed via a boss member (not shown) fixed to the wheel 2A.
- the front wheel brake disc 36A and the vehicle speed sensor rotor plate 34B are not in direct contact with each other. More specifically, frictional heat generated by the front wheel brake disc 36A is radiated by the wheel 2A.
- the front wheel brake disk 36A and the front wheel vehicle speed sensor unit 34 provided on the front wheel 2 have been described.
- the rear wheel brake disk 38A and the rear wheel vehicle speed sensor unit 35 provided on the rear wheel 3 are also described above. The same configuration as can be applied.
- the hydraulic unit 50 is configured as a unit for an electric brake device that performs an anti-lock operation and an interlocking braking operation.
- the hydraulic unit may be configured as a unit that performs only one of the antilock operation and the interlocking braking operation.
- it may be configured as a unit for controlling the brake pressure necessary for braking control such as traction control and wheelie prevention control by hydraulic pressure.
- the hydraulic unit 50 is configured as a unit for supporting braking control of both the front wheels 2 and the rear wheels 3.
- the present invention is not limited to this, and may be configured as a unit for supporting braking control of any one of the front wheels 2 and the rear wheels 3.
- the present invention provides a motorcycle including a hydraulic unit for performing a hydraulic control operation such as an anti-lock operation or an interlocking braking operation, and provides a space for other parts inside the main frame, and the hydraulic unit from the outside. This is useful for making it difficult for impact to be applied.
- a hydraulic control operation such as an anti-lock operation or an interlocking braking operation
