A wheel position detection device includes: a transmitter in each wheel of a vehicle having a first control unit for transmitting a frame with ID and an acceleration sensor; and a receiver on a vehicle body, including a second control unit for registering the ID in association with the wheel. The first control unit detects a wheel speed, and stores data of the acceleration sensor in the frame. The second control unit includes: a first determination device that determines a condition that the acceleration sensor is not in an on-state; a candidate registration device that registers a candidate of the ID of a spare wheel when the condition is satisfied; a second determination device that determines a travel history of the vehicle; and a registration device that identifies the ID of the spare wheel when the travel history is present, and registers the ID in association with the spare wheel.
