Claims

[Claims for Utility Model Registration] A connecting metal fitting whose upper part is an attachment part to an upper shelf, whose lower part is bent horizontally into a substantially L-shape, and where a pair of fitting grooves are provided on both side edges of the bent piece. And, while forming a substantially circular fitting hole inside,
It has a cam-shaped outer circumferential shape that is flattened relative to the fitting hole, and the opening edge of the fitting hole is fitted into the fitting groove of the bent piece of the connecting fitting so that it can freely rotate to the bent piece of the connecting fitting. An upper shelf connection device for a study desk, etc., consisting of a fastening fitting that is fitted onto the outside of the holder, and
