PROBLEM TO BE SOLVED: To provide a continuously variable valve device for an internal combustion engine controlling the valve lifting amount with high accuracy while increasing a speed of the rotation of an engine. SOLUTION: This continuously variable valve device has holding levers 18 for each of cylinders in a state of being vertically extended to a position adjacent to an oscillation lever 15, an upper end part of the holding lever 18 is supported rotatably on an oscillation supporting point A of an oscillation lever 15, and its lower end part is rotatably supported at a position to regulate a valve close state of an intake valve 4. Each oscillation lever 15 is held by the holding lever 18 in each cylinder in a state that the oscillation supporting point A is slidable along between an eccentric cam 12a and a driving cam 13a on the position to regulate the valve close state of the intake valve 4.
