A wheel position detector for a vehicle includes: a transmitter at each wheel having a first control portion for generating and transmitting a frame with specific identification information; and a receiver at a vehicle body receiving the frame from one wheel and having a second control portion for performing wheel position detection; and a wheel speed sensor for detecting a tooth of a gear. The second control portion: acquires gear information indicating a tooth position; corrects the tooth position based on a time difference between acquiring of the gear information and receiving time of the frame; and specifies the one wheel based on the tooth position at reception time.
