A variable valve lift apparatus may include a camshaft, a cam lobe including at least one low lift cam and at least one high lift cam, and formed or mounted on an exterior circumference of the camshaft, and a cam follower opening a valve with a low lift or a high lift or closing the valve by a rotation of the camshaft. The cam follower may include a valve lift body pivoting on one side and opening or closing the valve by the cam lobe when the camshaft rotates, a bearing shaft fixedly mounted in the valve lift body, and at least one rolling bearing rotatably mounted on the bearing shaft and being movable axially on the bearing shaft to make contact selectively with the low lift cam or the high lift cam.
