摘要： PROBLEM TO BE SOLVED: To obtain a motor-driving throttle valve controller with high rotation angle detection accuracy and high reliability by compactly forming a rotation angle detector of an inductance-type and non-contact type at an edge of a throttle shaft and easily assuring high positional accuracy.
SOLUTION: A cylindrical press-fit portion and a planar engaging portion are integrally formed in an exciting conductor successively in axial direction, a cylindrical portion and a planar portion are successively integrally disposed at a tip of a rotation axis, the planar engaging portion of the exciting conductor and the planar portion of the rotation axis are engaged to directly fix the cylindrical press-fit portion of the exciting conductor to the cylindrical portion of the tip of the rotation axis and to form a construction fixable at any position in axial direction for easily assuring high positional accuracy and high rotation angle detection accuracy and further two or more rotation stops are equipped, thereby the motor-driving throttle valve controller with the highly reliable rotation angle detector of inductance-type and non-contact type is obtained.
