Cord outlet structure of electric instrument cabinet

A cord outlet structure of an electric instrument cabinet, comprising:

• an opening window for forming a cord outlet;
• and
• a cover for opening and closing the opening window, wherein:
• the electric instrument cabinet made of a resin molding including the opening window and the cover;
• the cover being formed continuous with one of the sides of the edges of the opening window through a resin hinge composed of a thin part;
• the opening window is formed by and between the back wall and lower wall of the electric instrument cabinet, while the cover can be opened and closed back and forth with the resin hinge as a fulcrum, the resin hinge being provided on the edge of the opening window on the lower wall side of the cabinet;
• the cabinet is molded in such a shape that, when the cover is opened, the cover and cabinet can be evenly continuous with each other with the resin hinge between them;
• the opening window is formed such that it becomes smaller in width as it parts away from the resin hinge, thereby inclining the two side edges of the opening window inwardly;
• the cover is formed such that it becomes smaller in width as it parts away from the resin hinge, thereby inclining both side edges of the cover inwardly;
• the cover and opening window are formed such that, when the cover is closed to the opening window, the edges of the opening window and the side edges of the cover fitted into the opening window extend parallel to each other in their mutual adjacent positions or in their mutual contact positions;
• and
• integrally with both side edges of the opening window, there are formed cover receiver pieces each having a width smaller than horizontal clearances respectively formed between the side edges of the cover and the edges of the opening window when the cover is opened and the front and rear side portions of the cover holding the resin hinge between them are evenly continuous with each other, the cover receiver pieces capable of regulating the closing position of the cover.
