Title:
ROTATION ANGLE DETECTOR
Document Type and Number:
Japanese Patent JP2008070130
Kind Code:
A
Abstract:
To provide a rotation angle detector for use mainly in the rotation angle detection of a steering of a car which can be downsized and allows reliable rotation angle detection.
The upper part of a first detecting element 12 is engaged with a rotating element 1. The lower part of the first detecting element 12 is engaged with a second detecting element 13. The second detecting element 13 is arranged under the rotating element 1. This provides a rotation angle detector which can be downsized, can increase rotation angle detection accuracy easily by increasing the outer diameter and teeth number of the first detecting element 12 and the second detecting element 13, and allows reliable detection.
