Abstract
Since a front antenna 33 performs road-to-vehicle communication and vehicle-to-vehicle communication with oncoming vehicles, a nondirectional antenna enables effective communication in communication distances. Vehicle-to-vehicle communication with rearward vehicles by a rear antenna 37 needs long communication distances compared with road-to-vehicle communication and vehicle-to-vehicle communication with oncoming vehicles. The rear antenna 37 can also perform communication effectively with rear vehicles since what is selected is a directional one that can provide longer communication distances than a nondirectional one and that has directionality rearward of the vehicle. The front antenna 33 is disposed forward of a seat 7, and the rear antenna 37 is disposed rearward of the seat 7, which can inhibit an attenuation of electromagnetic waves due to the rider and the like. Consequently, while being capable of performing road-to-vehicle communication effectively, vehicle-to-vehicle communication with rearward vehicles can also be performed effectively.
