ABSTRACT:
An apparatus for monitoring the tire interior by supplying electric power from a power source on a chassis side to a tire-side sensor via a power-supplying coil and a power-receiving coil, and by transmitting a sensor output via a signal-transmitting coil and a signal-receiving coil. The signal-transmitting coil and the power-receiving coil, as well as the signal-receiving coil and the power-supplying coil, are respectively arranged to be substantially concentric in a respective substantially identical plane, and an electromagnetic shielding is provided so as to prevent noise from being mixed in the sensor output. The arrangement makes compact a coupling portion on the chassis side and a coupling portion on the tire side.
