Abstract
In an engine valve drive control device, a cam lobe is removably engaged with a cam shaft of a valve actuating line of an engine. The cam lobe is rotated, when engaged, together with the cam shaft to drive a valve. Free rotation of the disengaged cam lobe is halted by a cam rotation halting device to leave the valve inactive. The cam lobe is made axially slidable in the axial direction with respect to the cam shaft, and the engagement/disengagement of the cam lobe with/from the cam shaft are switched according to the sliding motion of the cam lobe.
