Disclosed herein is a valve driving apparatus. The valve driving apparatus includes at least one swing arm having one side corresponding to an upper side of a valve opening and closing a combustion chamber of an internal combustion engine; and a cam unit periodically pivoting the swing arm. Here, the swing arm performs a swing motion on the other side thereof by external manipulation to periodically compress the valve. The valve driving apparatus is capable of adjusting lift amounts of valves opening and closing a combustion chamber of an internal combustion engine. |
