Abstract
There is provided a construction for a cam rotation sensor attaching portion where a cam rotation sensor is attached which detect the rotation angles of camshafts ( ) supported on cam holders (lower cam holder , upper cam holder ), the construction being characterized in that portions to be detected (projections ) are provided on thrust plates ( ) fixed to axial ends of the camshafts so as to be brought into abutment with an axial end face (a thrust receiving face ) of the cam holder for regulating axial positions of the camshafts, and that a sensor (a proximity sensor ) for detecting the passage of the portions to be detected from an axial direction of the camshafts is attached to a member (a sensor attaching wall ) which is integrated into the cam holder. According to this construction, since the relative positioning accuracy between the portions to be detected and the sensor attaching portion with respect to the axial direction of the camshafts can easily be improved, a high detection accuracy can be obtained. Moreover, since the sensor and the head cover can be attached to and detached from the cylinder head without affecting each other, the maintenance and servicing properties thereof can be enhanced.
