PROBLEM TO BE SOLVED: To provide a device for monitoring air pressure in a tire of a vehicle having a plurality of wheels such as four wheels or six wheels, etc., by which the air pressure in a tire can be inspected easily. SOLUTION: A detection part 10 for detecting air pressure in a tire is provided to the wheel side of a vehicle, and an antenna 20c is provided to the body side in such a manner that it is opposite to the detection part 10, and further a monitoring part 20 is provided to such a position where a driver in a driving seat can recognize visually. Power supply energy is given the detection part 10 through electromagnetic waves from the monitoring part 20, and the detection part 10 sends the detection result to the monitoring part 20 through electromagnetic waves. The electromagnetic waves are received by the reception part of the monitoring part 20, and the detection results concerning air pressures in the respective tires are indicated on the monitor panel of a display 20b and an alarm is given in an emergency. |
