A continuous variable valve lift apparatus includes a cam(101), a first shaft, a second shaft(107), a roller(109), a first arm(111), and a second arm(115). The cam rotates by a cam shaft(103). The first shaft has a preset radius. The second shaft has a radius smaller than that of the first shaft, and is joined into the first shaft such that the first shaft is positioned at a different point in correspondence to the rotation of the second shaft. The roller moves in a vertical direction by the rotation of the cam, and is joined to the first shaft such that the roller moves from the point of the first shaft serving as a reference point. The first arm is joined to the second shaft such that the first arm is movable by the roller. The second arm is fixed to a third shaft(113) so as to open/close a valve(117) in accordance with the operation of the first arm.
