PURPOSE: A can lid structure is provided to easily open the can by converting the operating principles into a rotary tap method. CONSTITUTION: The structure comprises a can upper plate provided with an opening part(510) to be cut by a pressure, a tap pressurizing the opening part and a coupling portion(700) rotatably coupling the tap to the upper plate. The opening part(510) and the tap have concave and convex portions at the corresponding position. By the rotation of the tap around the coupling portion(700), the concave and convex portions deviated from their corresponding position to allow the tap to contact and pressurize the opening part(510), thereby cutting the opening part out from the can upper plate.
