PURPOSE:To simply make the slope of a top plate without a special work such as pressing, etc. by fitting a segmental beam on a side plate pressing the beam from below to above of the top plate after forming the top plate integrally with the side plate in nearly a flat shape. CONSTITUTION:An electric apparatus 1 has a cover 4 on it. A beam 5 has a segmental shape the center of which is higher than the ends. The projected side of the beam 5 is pressed and adhered closely to the bottom surface of a top plate 4b. Consequently, the top plate 4b is placed along the curved surface of the beam 5 and the top plate 4b is made to have a slope wherein the center is higher than the ends. In this construction, the cover 4 which has the slope in the top plate 4b can be manufactured without a work such as pressing or bending nor changing the construction of the cover 4 itself. |
