In a valve gear mechanism of an internal combustion engine, there is provided a valve opening and closing a combustion chamber, a spring device which generates a force pressing the valve toward a valve seat, a drive mechanism driving the valve in an opening direction via an operating section capable of being in contact with and separated from the valve, and a separation inhibiting device which inhibits a separation between the operating section and the valve.
