Abstract

Provided is a bearing device in which a magnetic ring is attached to a rotary member, a sensor unit, including a sensor, a wireless communication circuit, a power supply circuit, and a stator, is attached to a counterpart member, with the stator and the magnetic ring being radially opposed to each other. In the bearing device, the dimensions of the sensor unit are limited so as to reduce the space required for arranging the sensor unit and the magnetic ring. In the sensor unit (4), the stator (7) has a finite circumferential length. The stator (7), the sensor (11), the wireless communication circuit (12), and the power supply circuit (13) are arranged along a common circumference.
