Zusammenfassung:	PROBLEM TO BE SOLVED: To supply electric power to each tire sensor unit on the non-contact basis from the vehicle body side. SOLUTION: Electric power is transmitted wirelessly from a non-contact type power feeding part 40 (40a-40d) installed on the vehicle body to the tire sensor unit 10 (10a-10d) installed on the tire 2 (2a-2d). Transmitting the power wirelessly is conducted through electromagnetic coupling or using microwaves. The tire sensor units 10 are each equipped with a non-contact type power receiving part, which produces a DC power supply on the basis of the energy sent out from the power feeding part 40 and supplies an electric power necessary for operating the tire sensor units 10. The tire sensor units 10 sense the air pressure etc. and transmit the obtained information to a receiving device 20 wirelessly. COPYRIGHT: (C)2007,JPO&INPIT
