Abstract
To downsize a bearing assembly with a rotation detection device, a magnetic generating element () having a directionality about a rotation axis O is provided on an inner race () side of the bearing assembly (). A rotation sensor () capable of detecting a magnetism of the magnetic generating element () and outputting information descriptive of rotation or angle is fitted to an outer race () side in alignment with a bearing axis. The magnetic generating element () is fixed to a fixing member, for example, a rotary shaft () that is fixed to an inner diametric side of the inner race () of the bearing assembly ().
