Abstract
A valve opening and closing apparatus is disclosed having one or a plurality of rocker arms in contact with the cam, such that each of the rocker arms causes a valve to be opened and closed using the rotation of a cam. An eccentricity-creating unit is disposed on the rocker arm, and changes an eccentric position using rotation of a rotary shaft extending through the plurality of rocker arms. A driving unit is connected to the rotary shaft of the eccentricity-creating unit to rotate the rotary shaft.
