Abstract: PURPOSE: A variable valve lift device is provided to restrict the movement of a latching pin and prevent damage to an engine by preventing the rotation of the variable valve lift device. CONSTITUTION: A variable valve lift device comprises an inner tappet(200), an outer tappet(100), a latching pin, and a stopper.
