Abstract: A detection apparatus includes a base part, a bearing, a discoid rotating part for detection, and a displacement detection unit. The bearing has a first bearing member fixed to a rotating object, and a second bearing member fixed to the base part. The rotating part for detection is provided so as to rotate together with the first bearing member and extends radially outward of the bearing with respect to the first bearing member. The displacement detection unit is provided at a position in the base part which is radially away from the bearing and faces the rotating part for detection in an axial direction of the bearing. Moreover, the displacement detection unit is configured to output a voltage signal according to displacement of the rotating part for detection in the axial direction and displacement of the rotating part for detection in a direction perpendicular to the axial direction.
