ABSTRACT:
The present invention is related to an opening device for a microwave oven door. A hook is moved up and down to open/close the door. A swing lever moves the hook upwardly when swinging around a swing shaft at a predetermined angle. An elastic piece is protrudingly formed from an inside of the microwave oven to the swing lever for supporting the swing lever through one direction. By this construction, the elastic piece is deformed because the swing lever is swung. This bending restoring force restores the push button and swing lever to their initial positions, when the push button is released. As a result, the push button is restored without special spring part. Therefore, the number of parts is decrease, and the production cost is lowered. Also, the assembling work is improved, since the elastic piece is produced with swing lever integrally.
