A wheel position detecting device can suppress an erroneous detection of a wheel position even if a moving direction of a vehicle cannot be determined by wheel speed sensors whether in a forward direction or in a rearward direction. When an edge number (or a tooth number) is incremented based on detection signals of the wheel speed sensors of one, two or three wheels while the vehicle is at a halt, the edge number (or the tooth number) is not used as learning data. Thus, it is less likely that the wheel position is erroneously detected based on erroneous learning data. Therefore, even if the moving direction of the vehicle cannot be determined whether in the forward direction or the rearward direction by the wheel speed sensors, the wheel position detecting device can suppress the erroneous wheel position detection.
