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).
