This torque sensor is provided with: a sensor housing; a first sleeve that is attached to a first rotation member that rotates in relation to the sensor housing; a magnet attached to the first sleeve;a second sleeve that is attached to a second rotation member linked via a torsion bar to the first rotation member; a carrier attached to the second sleeve; a yoke that is attached to the carrier, and that faces the magnet in the radial direction which is orthogonal to the axial direction, which is the lengthwise direction of the first rotation member; and a magnetism collecting member that is attached to the sensor housing, and that faces the yoke in the axial direction. The carrier faces an opposing end surface of either the first sleeve or the magnet in the axial direction. The length in the axial direction of the gap between the carrier and the opposing end surface is less than the length in the axial direction of the gap between the yoke and the magnetism collecting member.
力矩传感器包括:传感器壳;第1套筒,其安装于相对于传感器壳旋转的第1旋转构件;磁体,其安装于第1套筒;第2套筒,其安装于借助扭杆而与第1旋转构件连结的第2旋转构件;保持部,其安装于第2套筒;磁轭,其安装于保持部并且在与第1旋转构件的长度方向即轴向正交的径向上面向磁体;以及集磁构件,其安装于传感器壳并且在轴向上面向磁轭。保持部在轴向上面向第1套筒和磁体中的一者所具有的相对端面。保持部与相对端面之间的间隙的轴向的长度小于磁轭与集磁构件之间的间隙的轴向的长度。
