WIPO Patent Application WO/2004/087439
Kind Code:
A1
Abstract:
A sensor device for a tire, having enhanced transmission capability without disturbing the assembly of a rim to the tire. With itself installed in the tire, the sensor device detects information inside the tire and transmits the result to the outside. The sensor device has a case for receiving an electronic component and an antenna electrically connected to the electronic component and extended to the outside of the case. The fore-end portion of the antenna is made to be displaceable to radially outside the tire by centrifugal force generated in the rotation of the tire.
