Zusammenfassung:	PROBLEM TO BE SOLVED: To surely give an alarm about a decrease in tire air pressure on the basis of an alarm threshold following a change in the air pressure in a tire, which is caused by traveling of a vehicle.SOLUTION: Tire air pressure data equivalent to a predetermined number of times of detection or the alarm threshold is prestored on a transmitter side, and a value obtained by lowering pressure by an alarm detection decompression rate from the maximum value of the prestored tire air pressure is set as the alarm threshold or the maximum value of the prestored alarm threshold is set as the alarm threshold. The tire air pressure detected on the transmitter side is compared with the set alarm threshold to detect the decrease of the tire air pressure. Thus, the alarm about the decrease of the tire air pressure can be surely given on the basis of the alarm threshold following the change of the air pressure in the tire, which is caused by the traveling of the vehicle.
