ABSTRACT:
A variable lift height valve driving device which drives a valve of an internal combustion engine, varying the lift height of the valve. An inner shaft is disposed in a hollow cam shaft to be capable of reciprocating along the axis. A primary cam which has a primary cam surface is fitted around the hollow cam shaft at a specified position, and a secondary cam which has a secondary cam surface is fitted to the primary cam. With movement of the inner shaft, the secondary cam moves such that the secondary cam surface is set in a position to be on a level with the primary cam surface or in a position to protrude outward from the primary cam surface.
