In a wheel position detecting device, a receiver acquires gear information indicating a tooth position of a gear rotating in association with a corresponding wheel at a predetermined interval. In a wheel position detection, the receiver sets a variation allowance range based on the tooth position at a reception timing of a frame transmitted from a transmitter integrated to each wheel. When the tooth position of the gear at a subsequent reception timing of the frame is not within the variation allowance range, the receiver excludes the wheel corresponding to the gear from a candidate wheel. The receiver registers the wheel remaining last as the wheel to which the transmitter is integrated. The receiver performs the wheel position detection only when a wheel speed is higher than a predetermined threshold, so that the wheel position detection is performed based on an accurate tooth position.
