Title:
DETECTING DEVICE FOR ROTATIONAL ANGLE
Document Type and Number:
Japanese Patent JP2001304805
Kind Code:
A
Abstract:

To expand a detection range of a detecting device for a rotational angle.

A first magnetic pole part 12a magnetized N pole and S pole around the rotation center, is provided inside of a magnet 12. A second magnetic pole part 12b magnetized opposite poles of the first magnetic pole part 12a, is provided outside of the magnet 12. A magnetoresistance sensor 15 is arranged on a position deviating from the rotation center of the magnet 12.
