PROBLEM TO BE SOLVED: To allow a lock mechanism function that surely performs the connection of the mounting of a shelf only by a hooking procedure in a gap between a wall surface and a shelf which is out of sight, and generates an adhesive action between the wall surface and the shelf by the procedure, and holds the state at the same time by preventing the mounting of the shelf from being disconnected.SOLUTION: A shelf mounting wall metal fitting is constituted of a hooking metal fitting fastened to a wall surface and an engagement metal fitting fastened to a shelf, which are respectively formed of a steel plate. The hooking fitting metal is formed with a front inclined piece by partial isolation at an upper end section, and formed to bent forward via the double refraction or single refraction of a lower end, and the front inclined piece is formed with a cut-out, and an elastic tongue piece housed therein is protruded in one of upward and downward directions, and the top end of the elastic tongue piece is formed with a protrusion on a rear face so as to be always more protruded than the rear face of the front inclined piece. The engagement metal fitting includes an engagement piece configured so as to be drawn to the wall surface with the boosting force of inclination according as it descends following the front inclined piece of the hooking metal fitting. As a lock mechanism for holding this hooking, the engagement piece is formed with an engagement hole in which the protrusion falls in accordance with the elastic deformation of the elastic tongue piece. |
