STEERING CONTROL DEVICE

To provide a steering control device which facilitates wiring attachment.SOLUTION: A first gear and a second gear are provided on the side of a first end 3c1 of a motor roller 3a in a direction of a rotation axis of a motor shaft 3c, and second teeth are provided on an outer peripheral side of a second gear body part, and the number of second teeth cannot be equally divided by the number of first teeth and vice versa. The steering control device includes: the second gear; a second magnet 10 which is provided in the second gear body part and has a first N pole and a first S pole being a pair of magnetic poles: a first magnetic sensor 11 which is provided in a position facing a first magnet 9a provided in the first gear and detects a rotation position of the motor shaft on the basis of a change in magnetic field of the first magnet due to rotation of the first magnet; and a second magnetic sensor 12 which is provided in a position facing the second magnet and detects a rotation position of the second gear on the basis of a change in magnetic field of the second magnet due to rotation of the second magnet.SELECTED DRAWING: Figure 2 【課題】配線取付けを容易に行うことができる操舵制御装置を提供する。【解決手段】モータシャフト３ｃの回転軸線の方向においてモータロータ３ａの第１端部３ｃ１側に、第１歯車と、第２歯車を備え、第２の歯は、第２歯車本体部の外周側に設けられており、かつ、第１の歯の数と互いに割り切れない数だけ設けられている。第２歯車と、第２歯車本体部に設けられ、１対の磁極である第１Ｎ極と第１Ｓ極を有している第２マグネット１０と、第１歯車に設けた第１マグネット９ａと対向する位置に設けられ、第１マグネットの回転に伴う第１マグネットの磁界の変化に基づき、モータシャフトの回転位置を検出する第１磁気センサ１１と、第２マグネットと対向する位置に設けられ、第２マグネットの回転に伴う第２マグネットの磁界の変化に基づき、第２歯車の回転位置を検出する第２磁気センサ１２とを有する。【選択図】図２
