1. A tire inflation pressure detecting device for detecting tire inflation pressure of a vehicle, comprising:
- tire inflation pressure sensors respectively arranged in a plurality of tires of the vehicle, for detecting respective tire inflation pressures;
transmitting units arranged in the tires respectively and in the vicinity of the tire inflation pressure sensors, for transmitting pressure data detected by the tire inflation pressure sensors; and
a receiving unit for receiving the pressure data transmitted by the transmitting units, whereinthe transmitting units are configured to transmit the pressure data, over a frequency, plural times at identical transmitting intervals at every predetermined cycle, the transmitting intervals being different from each other among the transmitting units, andthe receiving unit is configured to recognize the transmitting intervals of the pressure data transmitted from the transmitting units thereby identifying the transmitting units being as senders of the pressure data.

Abstract
A tire inflation pressure detecting device includes sensors provided in respective tires of a vehicle to detect various kinds of measured data involving a tire inflation pressure, transmitters for transmitting the measured data and a receiver for receiving the measured data transmitted from the transmitters. In operation, each of the transmitters of the tires transmits the measured data plural times at certain transmitting intervals in a predetermined cycle. Among the transmitters, the respective transmitting intervals are different from each other.
