Abstract: A variable valve operating system is provided to improve functions of a variable valve by constructing a valve device to have a mechanical structure instead of a hydraulic structure. A variable valve operating system comprises a cam follower(50) and a valve device. The cam follower includes an inner body(65) and an outer body. A locking member(60) is formed at one end of the inner body. The outer body surrounds a lateral portion of the inner body and is latched with the inner body by a latching device(70). If the inner body is latched with the outer body by the latching device, the inner and outer bodies perform the see-saw movement about a driving cam, thereby lifting an intake/exhaust valve(95) connected to the driving cam by a lost motion pin(90).
