ROTATION ANGLE DETECTION DEVICE

PROBLEM TO BE SOLVED: To provide an easily-assembleable device having a simple constitution, capable of detecting surely a rotation angle, concerning a rotation angle detection device mainly used for rotation angle detection of a vehicle steering, or the like. SOLUTION: A spur gear 21B as a connection means to a motor 15 is formed on a rotator 21 rotating sequentially with the steering. Hereby, since the connection means for connecting the motor 15 is formed integrally with the rotator 21, and a force of the motor 15 can be transferred to a steering shaft without using a different member, this easily-assembleable rotation angle detection device having the simple constitution, capable of detecting surely the rotation angle can be acquired.
