In a wheel position detector for a vehicle, a transmitter on each wheel repeatedly transmits a data frame containing identification information when an angle of the transmitter reaches a transmission angle. A receiver for receiving the frame is mounted on a body of a vehicle and performs wheel position detection based on the frame to specify a target wheel from which the frame is transmitted. The receiver acquires a tooth position of a gear rotating with a corresponding wheel when receiving the frame and sets a variation allowable range based on the tooth position. The receiver specifies the target wheel by determining whether the tooth position falls within the variation allowable range. The transmitter changes the transmission angle at a predetermined time interval.
