Abstract
While an operating angle or a lift of an engine valve () is modified within a predetermined operating angle range or lift range, variation in an opening timing of the engine valve () is suppressed by displacing a rocker shaft () relative to a drive shaft () such that an opening timing variation of the engine valve () accompanying angular variation in a straight line linking a center of the drive shaft () and a center of the rocker shaft () and an opening timing variation of the engine valve () accompanying variation in a distance between the center of the drive shaft () and the center of the rocker shaft () cancel each other out.
