摘要： A variable valve lift apparatus includes a high cam and a low cam fixed side by side to a camshaft, an outer body pressed by the rotation of the high cam, and has a crossbar formed at the bottom of the front end, an inner body, of which the front end protrudes further than the outer body, the lower front end is provided with a valve member, the upper rear end is hinged to a lost motion hinge shaft coaxially with the rear end of the outer body, and the lower rear end is pivotally connected to a hinge member, and a latching portion inserted into the inner body and selectively connected to the crossbar of the outer body to move the inner body dependent on movement of the front end of the outer body, wherein the lost motion hinge shaft is disposed in the same direction as a hinge point between the inner body and the hinge member with respect to the camshaft. Dynamic characteristics can be obtained by reducing the moment of inertia of the variable valve lift apparatus, and the dynamic characteristics can be further improved by inserting the latching portion into the inner body so as to be closer to the camshaft.
