PURPOSE:To prevent the radiation of noise by an inexpensive method by so disposing, at a position where the opposed molded member ends of a housing, and a cover are brought into contact without gap, as not to form a gap between clamping faces of opposed plate members of the housing the cover, and clamping the housing, and the cover by deforming the plates. CONSTITUTION:A bottom cover M5 is composed of a molded bottom M29 and a bottom plate M30, and both are integrated by thermally caulking. A body cover M6 is brought into contact with the bottom M29 in a state that the cover M5 is mounted, but the plate M30 is held at a gap of 0.5mm from a plate chassis M12. Seven holes are opened at the bottom M29, and screws are inserted therefrom to clamp the plate M30 to the chassis M12, thereby mounting the cover M5. As a result, boards, a hard disk drive M11, etc., can be shielded by the chassis M12 and the plate M30 to provide an effect of suppressing noise. The cover M6 and the bottom M29 are engaged with one another by a deforming force of 0.5mm of the plate to be aligned without gap. |
