PROBLEM TO BE SOLVED: To provide a torque sensor capable of suppressing protrusion in a radial direction thereby improving mount-ability to a vehicle.SOLUTION: A torque sensor 100 for detecting torque acting on an input shaft 3, based on magnetic change caused by relative angle displacement of the input shaft 3 and an output shaft 5 being rotatably supported in a housing 7, comprises: a detection part 50 for detecting magnetic change, through a penetration hole 73 which is formed by penetrating a radial side surface of the housing 7; a storage chamber 72 which is formed by projecting outward of the radial direction from an outer peripheral surface of the housing 7, the penetration hole 73 opens therein, and which stores the detection part 50; a communication hole 74 extending in a tangential direction to the outer periphery of the housing 7, and communicating outside of the housing 7 and inside of the storage chamber 72; and an output terminal 81 fitted and attached to the communication hole 74, connected to and inclined to the detection part 50 and outputting a signal based on the detection signal to outside.SELECTED DRAWING: Figure 8

    【課題】径方向への張り出しを抑制して車両に対する搭載性を向上させることが可能なトルクセンサを提供する。【解決手段】ハウジング7内に回転自在に支持された入力軸3と出力軸5との相対角度変位による磁気的変化に基づいて入力軸3に作用するトルクを検出するトルクセンサ100は、ハウジング7の径方向側面に貫通して形成される貫通孔73を通じて磁気的変化を検出する検出部50と、ハウジング7の外周面から径方向外側に隆起して形成され内部に貫通孔73が開口するとともに検出部50を収容する収容室72と、ハウジング7の外周に対する接線方向に延設されハウジング7の外部と収容室72の内部とを連通する連通孔74と、連通孔74に嵌装されるとともに検出部50に対して傾斜して接続され検出信号に基づく信号を外部へ出力する出力端子81と、を備える。【選択図】図8
