SOLUTION: A panel 2 is guided into a guide rail 1a and is inserted into a shelf 1, an ejector 3 that is fitted to the panel 2 is gear-locked to an ejector guide 6 being extended left and right being provided at the front end of the shelf 1 at the inside at a final stage, and the panel 2 is pushed into the shelf 1 based on the principle of a lever with the point as a support point 6b. At this time, an erroneous insertion prevention rib 3a that the ejector 3 has is guided so that it passes through an erroneous insertion prevention rib guide groove 6a located at the ejector guide 6. Then, after the panel 2 has been loaded completely, a lock 4 is locked to the ejector 3, thus preventing erroneous insertion.
