置。 A vehicle-to-vehicle gap that measures an inter-vehicle distance by transmitting a response wave from a preceding vehicle in response to a transmission wave from a following vehicle, and measuring a time difference between transmission of the transmission wave and reception of the response wave in the following vehicle. In the distance measuring device, the response wave transmitter that transmits the response wave includes a level detector that detects the reception level of the incoming transmission wave, and a detection level that is variable controlled by the output of the level detector. An inter-vehicle distance measuring device comprising: a no-signal detector.
