ABSTRACT:
In a variable valve system for an internal combustion engine and its driving mechanism, the variable valve system comprises: a variable mechanism that revolves a control axle to change an operation characteristic of an engine valve; a projection section projected at an outer peripheral predetermined position in an axial direction of the control axle and on a tip of which a fixture section is formed; a fixture member fixed in a grasped state for the projection member via an engagement member engaged on the fixture section; a driving mechanism configured to provide a rotating force for the control axle via the fixture member; and control means (a control section) for controlling the driving mechanism in accordance with a driving state of the engine.
