To provide a vehicular detection device capable of enhancing accuracy of detecting displacement.SOLUTION: A detection device comprises: a stator base portion 42 fixed to a vehicle body of a vehicle; and a bearing 50. The bearing 50 has an outer ring 51, an inner ring 52, and rolling elements 53 provided between the outer ring 51 and the inner ring 52, and supports a wheel so as to be rotatable relative to the stator base portion 42. The inner ring 52 is fixed to the wheel, and the outer ring 51 is fixed to the stator base portion 42. The detection device comprises: a disk-shaped race portion 80 that is fixed to the inner ring 52 and extends radially outward of the bearing 50; and a detection unit 90. The detection unit 90 is provided at a position, which is away from the bearing 50 in a radial direction and faces the race portion 80 in an axial direction of the bearing 50, on the stator base portion 42.SELECTED DRAWING: Figure 1 【課題】変位の検出精度を高めることができる車両用検出装置を提供する。【解決手段】検出装置は、車両の車体に対して固定される固定子ベース部４２と、軸受５０とを備えている。軸受５０は、外輪５１、内輪５２、及び外輪５１と内輪５２との間に設けられる転動体５３を有し、車輪を固定子ベース部４２に対して回転可能に支持する。内輪５２が車輪に対して固定され、外輪５１が固定子ベース部４２に対して固定されている。検出装置は、内輪５２に対して固定され、軸受５０の径方向外側に延びる円盤状のレース部８０と、検出ユニット９０とを備えている。検出ユニット９０は、固定子ベース部４２のうち、径方向において軸受５０から離れた位置であって、軸受５０の軸方向においてレース部８０と対向する位置に設けられている。【選択図】 図１
