Claim:
1. An on-board wireless device, which is used in a subject vehicle and transmits a vehicle information of the subject vehicle to a periphery vehicle positioned around the subject vehicle, the on-board wireless device comprising: a transmitting circuit successively transmitting the vehicle information of the subject vehicle via a vehicle-to-vehicle communication at a transmission interval; a transmission interval setting section setting the transmission interval that is variable for transmitting the vehicle information; a generation section generating the vehicle information to be transmitted by the transmitting circuit, the generation section including a transmission interval related information in the vehicle information, the transmission interval related information being an information based on which the transmission interval set by the transmission interval setting section can be specified, the transmitting circuit transmitting the vehicle information of the subject vehicle, which includes the transmission interval related information, to the periphery vehicle; a parking detection section detecting a parking state of the subject vehicle; and a hazard detection section detecting an on state or an off state of a hazard lamp of the subject vehicle, wherein when the parking detection section detects the parking state of the subject vehicle and the hazard detection section detects the on state of the hazard lamp, the transmission interval setting section sets the transmission interval to have a first value, when the parking detection section detects the parking state of the subject vehicle and the hazard detection section detects the off state of the hazard lamp, the transmission interval setting section sets the transmission interval to have a second value, and the second value is greater than the first value.
