There was an unreasonable aspect to it that it was complicated.

Therefore, the present invention aims to eliminate this unreasonableness and provide a support arm mounting device that can be adapted to any case where the mounting wall surface is soft or hard.

"Means for Solving the Problems" As a means for solving the above problems, the article support body is attached to a mounting seat plate, a support arm fitted to the front surface of the mounting seat plate, and a ring body fitted to the fitting portion of both. It consists of The mounting seat plate is provided with a protruding part at the center of its front surface, and a plurality of through holes are drilled on the protruding part so as to penetrate all the way to the bottom surface, and tile pins are inserted into the plurality of through holes. At the same time, a pair of left and right wood screw insertion holes are provided on both sides of the raised portion so that the wood screws can be screwed into the wall surface through these holes, and an adhesive means is provided on the bottom surface (back surface). An engagement groove for the ring body is provided, and a convex edge is provided forwardly along the inside of the outer peripheral edge.

Further, the support arm has a diameter larger than that of the front end so that the base end fits into the forward convex edge of the mounting seat plate, and a step portion for attaching the ring body is formed along the outer peripheral surface of the base end. , the whole is formed in a hollow shape, and a window hole for inserting an article-locking rod is provided at the front end.
