ABSTRACT:
A microwave oven including a cabinet defining a cooking chamber therein, and a door coupled to the cabinet to open and close the cooking chamber. The door includes a door frame forming an appearance of the door, a shielding plate installed in the door frame to prevent high-frequency electromagnetic waves from radiating from a small gap between the door and the cabinet, a choke member provided at a peripheral edge of the shielding plate and having a high-frequency choke groove, a cover to cover the high-frequency choke groove, and a retaining member provided at the cover to elastically support the choke member. When the cover is attached to the choke member, an end of the choke member is supported on an inner rib section of the cover via the retaining member, thus reducing deformation of the choke member.
