A second transmitting antenna (26) is disposed so as to allow communication in a second range (31) that accommodates the transmitting and receiving unit (11) attached to the first wheel and does not accommodate the transmitting and receiving unit (10) attached to the second wheel. A controller (21) associates an identification code of the transmitting and receiving unit (11), which has received request signals from the first and second transmitting antennas (25) and (26) and has transmitted response signals, with a region shared by the first and second ranges (30) and (31), and associates an identification code, assigned to the transmitting and receiving unit (10), other than the identification code associated with the region with a region inside the first range (30) and outside the second range (31).",
