To provide a torque sensor that can suppress deterioration of detection accuracy.SOLUTION: A torque sensor includes a sensor housing, a first sleeve attached to a first rotating member that rotates with respect to the sensor housing, a magnet attached to the first sleeve, a second sleeve attached to a second rotating member coupled to the first rotating member via a torsion bar, a carrier attached to the second sleeve, a yoke attached to the carrier and facing the magnet in a radial direction orthogonal to a shaft direction that is a longitudinal direction of the first rotating member, and a magnetic flux collecting member attached to the sensor housing and facing the yoke in the shaft direction. The carrier faces an opposing end surface of either one of the first sleeve and the magnet in the shaft direction. Length of a gap between the carrier and the opposing end surface in the shaft direction is smaller than length of a gap between the yoke and the magnetic flux collecting member in the shaft direction.SELECTED DRAWING: Figure 7

    【課題】検出精度の低下を抑制できるトルクセンサを提供すること。【解決手段】トルクセンサは、センサハウジングと、センサハウジングに対して回転する第1回転部材に取り付けられる第1スリーブと、第1スリーブに取り付けられるマグネットと、トーションバーを介して第1回転部材と連結された第2回転部材に取り付けられる第2スリーブと、第2スリーブに取り付けられるキャリアと、キャリアに取り付けられ且つ第1回転部材の長手方向である軸方向に対して直交する径方向でマグネットに面するヨークと、センサハウジングに取り付けられ且つ軸方向でヨークに面する集磁部材と、を備える。キャリアは、第1スリーブ及びマグネットの一方が有する対向端面に軸方向で面している。キャリアと対向端面との間の隙間の軸方向の長さは、ヨークと集磁部材との間の隙間の軸方向の長さよりも小さい。【選択図】図7
