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. The latching pin inserted inside the inner tappet forms a high lift and a low lift by connecting the inner tappet and the outer tappet selectively. A part of the stopper inserted the outer tappet restricts the movement of the latching pin and separated from the latching pin in the moving direction of the latching pin. The stopper protruding from the outer tappet prevents the variable valve lift device from rotating by sliding in a groove of a cylinder head.
