<p>In a wheel location detector device, a first control unit (23) of a transmitter (2) transmits a frame when an increase/decrease direction of a value of a gravitic acceleration component which is included in a detection signal of an acceleration sensor (22) which is detected for each of a prescribed time interval is contiguous in the same direction. On the basis of detection signals of wheel acceleration sensors (11a-11d), a second control unit (33) of a receiver (3) acquires gear information which denotes teeth locations of gears (12a-12d), and carries out wheel location detections on the basis of the gear information at the receiving timing of the frame.</p> |
