Claims (1)

[Scope of utility model registration request] In a chassis used for electronic equipment, a panel made of a resin material with a convex portion with a flat upper end surface is attached to the frame of the chassis, and on the back side of the panel there is a vertical direction in the center of the convex portion. a first rib provided perpendicularly to the panel surface, the upper end surface of which has the same height and depth as the upper end surface of the convex portion; a second rib parallel to the upper edge and perpendicular to the same side wall surface; a protrusion piece having a claw at the tip formed on the upper end of the convex portion outside the first rib; and on the front side of the panel. two third ribs, each of which has an upper end surface the same height as the upper end surface of the convex part in the vertical direction on both sides of the protruding piece, and are provided perpendicularly to the panel surface; and a claw provided on the protruding piece. grooves provided on both sides of the location where the two third ribs are parallel to each other, and grooves provided on the upper end of the convex portion on the opposite side of the protruding piece outside the first rib. The panel consists of a boss having a screw hole on the surface side, and a unit chassis whose periphery is covered with a metal plate and the same metal plate is flat, and the metal plate has a rectangular through hole on the edge side of the central part of the side surface. a first cut and cut that fits into the groove, and a second cut and cut that has a notch on the edge of the side surface of the metal plate at a location obliquely away from the first cut and cut; and a mounting foot provided with a bent portion having a screw hole perpendicular to the plane on which the first cut and cut is provided on the edge of the same side surface opposite to the location where the first cut and cut is provided. , the unit chassis provided such that the first cut and cut, the second cut and raise, and the mounting feet are parallel to each other, and the first cut and cut, the through hole of the cut and A chassis structure in which the notch of the second cut-and-raised part and the screw hole of the mounting foot correspond to the groove, the claw of the projection piece, the second rib, and the screw hole of the boss, respectively, so that the unit chassis is mounted on the panel. .
