TIRE EQUIPPED WITH INFORMATION ACQUISITION DEVICE

摘要

In a virtual plane which contains a coil axis (C) of a coil-shaped antenna (450) and has a vertical line (P) that is perpendicular to a rotation axis (x) of a tire, an information acquisition device is provided in such a manner that the angle formed between the rotation axis (x) of the tire and the coil axis (C) of the antenna (450) falls within the range from 0 to 40 degrees. This constitution enables the reduction in the attenuation amount of a radiowave that is emitted from the antenna (450) toward the outside of the tire.
