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.

Abstract: A detection device for vehicles includes a base section fixed to a body of a vehicle, and a bearing having an outer ring member, an inner ring member, and rolling elements, which rotatably supports a wheel of the vehicle against the base section. A first bearing member of the outer ring member and the inner ring member is fixed to the wheel, and a second bearing member of the outer ring member and the inner ring member is fixed to the base section. The detection device includes a disk-shaped rotating section for detection that extends radially outward of the bearing with respect to the first bearing member, and a displacement detection section that outputs a signal in response to an axial displacement of the rotating section for detection.
