Abstract: An installation structure for an electronic component for a tire, where a case for the electronic component attached to a rim well portion can be prevented from being destroyed during attachment and removal of the tire to and from a wheel. In the installation structure, the electronic component received in the case is attached to the rim well portion in a tire air chamber. When the case is subjected to external force applied in the radial direction of the tire, the case is positionally released from a fixed state before it is destroyed by the force.

Abstract: An installation structure of an electronic component for a tire, where the installation structure protects the electronic component from heat produced by a tire and a braking device and enables accurate information about the inside of the tire to be obtained without being affected by the heat sources.

Abstract: In a pneumatic tire (20) on which a transponder (1) is mounted, a securing member (3) for securing the transponder (1) is fixed to an inner surface of the tire in an area (S) between a tire maximum-width position (A) and a bead toe (B). Thereby, a large centrifugal force and a large impact force do not act on the transponder (1) storing various pieces of information, and the transponder can be mounted quickly and securely. Also, the weight of the transponder is remarkably reduced, and thus uniformity of the tire (20) is enhanced. Additionally, dynamic balance correction is made easier. Even in a large tire, reduction in durability is minimized through suppressing heat generation and heat accumulation of the tire (20) due to the transponder (1) and the securing member (3).

Abstract: There is provided a vehicle abnormality detection method detecting an abnormal state in which a high temperature occurs due to maladjustment of a vehicle bearing mechanism section or vehicle brake mechanism section, and a device thereof and a sensor unit thereof. By use of the sensor unit 100 mounted in a rim 31, an air temperature within a tire 2 is sensed as a first temperature and a temperature (second temperature) of the rim 31 is sensed as a temperature related to at least one of a temperature of the vehicle bearing mechanism section and a temperature of the vehicle brake mechanism section 40. Then a temperature difference between the first and second temperatures is calculated and when the temperature difference is a predetermined value or more, it is determined that an abnormality has occurred in the vehicle bearing mechanism section or vehicle brake mechanism section 40. The abnormality is thus detected.
