Abstract:
A valve timing control apparatus for an internal combustion engine includes a driving rotation member to which rotation of a crankshaft is transmitted, a driven rotation member coupled to a camshaft so as to be rotatable relative to the driving rotation member, an electric motor having a motor output shaft to cause rotation of the driven rotation member relative to the driving rotation member, a cover member arranged axially facing a front end portion of the motor output shaft and an electromagnetic induction type rotational angle detection mechanism disposed between the motor output shaft and the cover member so as to detect a rotational angle of the motor output shaft. The rotational angle detection mechanism has a detected part provided to the front end portion of the motor output shaft and a detecting part provided to a portion of the cover member axially facing the detected part.
