A valve actuating link is provided for transmitting a combined movement of a drive cam on a cam shaft and a control cam on a control shaft to a valve pressing structure of an engine valve. The valve actuating link comprises a bearing portion that bears the control shaft, a hook-shaped lower portion that surrounds the cam shaft keeping a given space therebetween and a cam portion that repeatedly pushes the valve pressing structure to induce an open/close operation of the engine valve. Each of a plurality of engine valves has its own respective drive cam, control cam, valve actuating link and valve pressing structure.
