もつて対向する磁気抵抗素子を有し、該回転体の
回転に伴つて前記磁気抵抗素子に印加する磁界が
変化し、前記磁気抵抗素子の抵抗値が変化するこ
とで回転角度を検出する装置において、前記回転
体の回転方向を４５°傾けて、前記磁極を構成し
、かつ、前記磁気抵抗素子も同様に傾けたことを
特徴とする回転角度検出装置。 It has a rotating body having a magnetic pole on its outer periphery, and a magnetoresistive element facing the magnetic pole with an air gap, and as the rotating body rotates, the magnetic field applied to the magnetoresistive element changes, and the magnetic field of the magnetoresistive element changes. A device for detecting a rotation angle by a change in resistance value, characterized in that the rotation direction of the rotating body is tilted by 45 degrees to form the magnetic pole, and the magnetic resistance element is also tilted in the same manner. Angle detection device.
