In a wheel position detection apparatus, a first control unit (23) of a transmitter (2) repeatedly transmits a frame including unique identification information at the timing when the angle of the transmitter (2) is at a predetermined angle. A second control unit (33) of a receiver (3) receives the frame transmitted from the transmitter (2), and identifies which of a plurality of wheels (5a to 5d) the transmitter (2) that has transmitted the frame is attached to. The receiver (3) modifies an allowable variation range in accordance with a road surface condition expressed by the degree of road surface roughness each time the frame is received, and sets the allowable variation range wider for a rough road surface than for a smooth road surface.
