Provided is a valve operating apparatus for an internal combustion engine that, with respect to a configuration including urging means that urges a transfer member that transfers an acting force of a cam to a valve, can facilitate manufacture of a support portion of the urging means and suppress an increase in the mass of the internal combustion engine. A first rocker arm (18) is provided that is interposed between a main cam (14) and a valve (26) and that transfers an acting force of the main cam (14) to the valve (26). A lost motion mechanism (60) is provided that urges the first rocker arm (18) in one direction. A holding member (68) is provided that holds the lost motion mechanism (60). The lost motion mechanism (60) is attached to a spark plug tube (66) through the holding member (68).
