PROBLEM TO BE SOLVED: To provide a simple, light-weight, low-cost variable valve train variably controlling valve lift quantity. SOLUTION: A control arm 6 is disposed in such a manner that the same can rock between a swing arm 7 and a rotation cam 4 of a variable valve train 1. The control arm 6 includes a pair of control levers. The pair of control levers moves together in a rotation direction around a control shaft 5, but can move in only one direction of an axial direction of the control shaft 5, and an interval between the same is variable. The control arm 6 interlocks with rotation of a rotary cam 4. When the roller 8 of the swing arm 7 is pushed down, push down quantity of the roller 8 is changed by changing the interval of the pair of control levers of the control arm 6 to change the valve lift quantity.
