To provide a steering gear including a torque sensor with an axial distance between a stator and a magnetism collecting yoke hardly changeable.SOLUTION: A steering gear 80 includes: a housing 200 including a first step part 210 and a second step part 220; a shaft 300 including a third step part 230; a first bearing 70; a second bearing 77; a nut 120 fixed to the shaft 300; and a torque sensor 10 including a stator 50 fixed to the shaft 300 and a magnetism collecting yoke 43 fixed to the housing 200. In a state of attaching the shaft 300 to the housing 200, tensile forces P1 and P2 extending in a D direction acts in an area between a part positioned on the inner peripheral side of the first bearing 70 and a part positioned on the inner peripheral side of the second bearing 77 in the shaft 300.SELECTED DRAWING: Figure 13 【課題】ステータと集磁ヨークとの軸方向距離が変化しにくいトルクセンサを備える操舵装置を提供すること。【解決手段】操舵装置８０は、第１段差部２１０と第２段差部２２０とを有するハウジング２００と、第３段差部２３０を有するシャフト３００と、第１軸受７０と、第２軸受７７と、シャフト３００に固定されるナット１２０と、シャフト３００に固定されるステータ５０と、ハウジング２００に固定される集磁ヨーク４３とを含むトルクセンサ１０と、を備える。シャフト３００をハウジング２００に組み付けた状態で、シャフト３００において、第１軸受７０の内周側に位置する部位と第２軸受７７の内周側に位置する部位との間の領域には、Ｄ方向に延びる引張力Ｐ１、Ｐ２が作用する。【選択図】図１３
