ABSTRACT:
A camshaft rotational detection structure is configured that can improve the precision with which the camshaft rotational angle is detected. The camshaft rotational detection structure detects the rotational angle of a camshaft to which rotation is transmitted from the crankshaft of an engine through a cam sprocket mechanism. The camshaft rotational detection structure is provided with a cam thrust flange, a detection target, and a sensor. The cam thrust flange is provided on the camshaft near the end of the camshaft where the cam sprocket mechanism exists and serves to restrict axial movement of the camshaft. The detection target is provided on the cam thrust flange. The sensor is arranged facing opposite the detection target and is configured to detect the rotational angle of the camshaft.
