A vehicle is mounted with a pulse detecting unit that detects rotation of a wheel as pulses, a wheel rotation number storage unit that stores the number of pulses in correspondence with time, and a wheel position specifying device that specifies on which of the plurality of wheels the tire state detecting device arranged on each wheel is arranged. The wheel position specifying device includes a reception unit that receives a transmission signal, including a time required for the wheel to make a predetermined number of rotations, transmitted from each tire state detecting device, and a specifying unit that specifies the wheel on which each tire state detecting device is arranged from a difference of the number of pulses counted during the time included in the transmission signal and the number of pulses while the wheel makes the predetermined number of rotations.
