PROBLEM TO BE SOLVED: To provide an adjustable valve mechanism of an engine capable of controlling the valve property of an engine valve with high precision, maintaining the structure of existing equipment to the utmost. SOLUTION: The adjustable valve mechanism is provided with an intermediate drive mechanism installed in each cylinder. Each intermediate drive mechanism is provided with an input arm 36, a first output arm 41 and a second output arm 42 at both sides in the axial direction. A torsion angleθ1 of a helical spline 41b installed in the first output arm 41 is set larger than a torsion angleθ2 of a helical spline 42c installed in the second output arm 42.
