ABSTRACT:
A rotation angle detector is provided with a spring to thrust a rotary body against protrusions formed on an inner wall of an opening via a detector body in a manner to keep the rotary body rotatable without any play in a linked motion with a steering shaft. As a result, the detector can detect rotation angles of the steering shaft with high accuracy.
