An object of the invention is to provide a method for easily molding projections on an end edge along an opening in a housing which project towards an opposite side of the end edge to the opening, and to provide a housing structure related to the method. The invention relates to a method for molding a housing, including molding an end edge ( 6 ) which extends outwardly of an opening ( 4 ) in a housing ( 1 ) such that a closing member ( 5 ) for closing the opening ( 4 ) is locked thereto by using a first mold ( 30 ) having a grating-like portion and a second mold ( 40 ) adapted to alternately mesh with the grating-like portion of the first mold ( 30 ), and forming an projection ( 28 ) which projects towards an opposite side to the opening ( 4 ) on an outer side of the end edge ( 6 ) by drawing out the grating-like portion of the first mold ( 30 ) which penetrates the end edge ( 6 ) towards the opening ( 4 ) side which is opposite to an end portion of the grating-like portion and drawing out the second mold ( 40 ) from the end edge ( 6 ) position outwardly of the housing ( 1 ).
