Abstract: This invention relates to an opening and closing apparatus for a door of a microwave oven which has lighting lamps. The door of the microwave oven is devised to have a predetermined time until it is opened in a course of power transmission by a driving motor by which the door is opened and closed. The driving motor rotates a driving gear and the driving gear makes an opening and closing lever move linearly. Accordingly the door which is locked with the main body of microwave oven can be opened by the linear motion of the opening and closing lever. Therefore, the door is opened after a predetermined time is passed by the fact that the power transmission from driving motor is delivered to the opening and closing lever through the driving gear so that the remaining light by the lighting lamps can be completely removed. This can prevent the user's eye being damaged by the remaining light and improve the value in use for the microwave oven with lighting lamps.
