PROBLEM TO BE SOLVED: To facilitate operation of a worker when learning a wheel position after rotation of the wheel. SOLUTION: Wheel side devices 20-28 transmit wheel information when an air pressure of a tire is rapidly varied. In this case, the order for rapidly varying the air pressure of the tire is predetermined. Accordingly, in a vehicle body side device 30, the wheel information is expected to be received in the order decided corresponding to the rules. In the vehicle body side device 30, the position of the wheel provided with the wheel side device to which the wheel information is transmitted can be obtained based on the receiving state of the wheel information and the rules. The worker may vary the air pressure of the tire in the order decided by the rules and it is not needed to repeat input work of the wheel position and rapid varying work of the air pressure of the tire alternately. The work can be facilitated by that degree. Further, input of the wheel position can be more certainly performed. COPYRIGHT: (C)2005,JPO&NCIPI |
