1. A wheel assembly position identifying apparatus configured to be mounted in a vehicle equipped with rotational position detecting sections, each of which detects a rotational position of one of wheel assemblies, the apparatus comprising:

  • transmitters, each of which is provided in one of the wheel assemblies; and

    a receiver, which is provided in a body of the vehicle, whereineach transmitter includesa transmission section, which is configured to transmit a position detecting signal to the receiver, anda control section, which is configured to cause the transmission section to continuously transmit the position detecting signal for at least a predetermined transmission time, andthe receiver includesa receiving section, which is configured to receive the position detecting signal,a measuring section, which is configured to measure a received signal strength indication (RSSI) of the received position detecting signal, anda wheel assembly position identifying section, which is configured todetect, more than once, a rotational position of each wheel assembly at which the RSSI has an extreme value, for each position detecting signal received during one rotation of the wheel assembly, andidentify the position of the wheel assembly in which the corresponding transmitter is provided based on variation of the rotational position of the wheel assembly at which the RSSI has the extreme value.
