1. A rotational angle detecting device, comprising:

  • a rotor having targets disposed on the circumferential surface of said rotor, said targets being made of magnetic material and inclined with respect to an axial direction of said rotor; and

    plural magnetoresistance effect elements for detecting the position where magnetic change occurs in an axial direction of said rotor;

    wherein a displacement angle of said rotor from said plural magnetoresistance effect elements is detected on the basis of the positions detected by said plural magneto resistance effect elements.
