A microwave oven structure whose constituent members can be easily and firmly assembled without using a spot-welding process. In given mating members to be joined, through-holes are formed in one of the mating members and squeezed or cut-and-raised projections are formed on the other mating member at positions corresponding to the through-holes whereby the mating members are joined with each other by rolling-over method in which the projections are inserted into the through-holes and caulked by rolling over or bonding the projections. |
