A wheel assembly position identifying apparatus includes transmitters, each of which is provided in one of wheel assemblies, and a receiver, which is provided in a body of a vehicle. Each transmitter includes a transmission section, which is configured to transmit signals to the receiver, an acceleration sensor, which is configured to rotate together with the corresponding wheel assembly and detect acceleration acting on the acceleration sensor, and a transmission-side control section, which is configured to cause the transmission section to transmit a constant position signal and a position detecting signal. The constant position signal is transmitted at a constant position based on the acceleration detected by the acceleration sensor. The position detecting signal is transmitted at a constant power. The receiver includes a reception section, which is configured to receive the signals, and a reception-side control section, which is configured to execute a first identifying process and a second identifying process. In the first identifying process, the positions of the wheel assemblies, in which the corresponding transmitters are provided, are identified based on variations of the rotational positions of the wheel assemblies at the time when the constant position signals are received. In the second identifying process, the positions of the wheel assemblies, in which the corresponding transmitters are provided, are identified based on the received signal strength indications (RSSIs).
