A cavity structure for an oven is provided to prevent damage to the enameled surface of the oven by spacing a joint member for joining components to a cavity from the enameled surface. A cavity structure for an oven includes a sheet for forming an outer appearance of a cavity, a first joint unit(400) having a joint hole for joining components to the sheet, a joint component having a second joint unit(500) mating to the first joint unit, and a joint member inserted to the first joint unit and the second joint unit. At least one of the first joint unit and the second joint unit has a projection formed through a burring process so as to prevent the joint member from contacting the inner surface and/or the outer surface of the sheet when the joint member is inserted.
