Abstract
To provide a wheel support bearing device, in which the status of actual use is detected and stored as a history, an IC tag () capable of a contactless communication is affixed to the wheel support bearing device. This IC tag () is rendered to be a sensor incorporated IC tag integrated with or electrically connected with a sensor for detecting an object to be detected of the wheel support bearing device and a detection of the sensor is inputted through an input channel separate from a channel for the contactless communication. The sensor referred to above may be, for example, a coil and a magnet () capable of passing in the vicinity of the sensor incorporated IC tag () by the effect of a relative rotation.
