Claims

[Claims for Utility Model Registration] (1) Two annular standing walls are provided in parallel at equal intervals on one side of the flat plate part, and the gap between the compatible walls is an annular opening facing the opposite side of the flat plate part, and at least one of the compatible walls is Two or more places on the entire circumference of one standing wall are cut out to form notches, and in the notches, protrusions with protrusions on the side facing the annular opening are erected to serve as locking pieces made of synthetic resin. Annular body A, and two parallel strips set on one side of the flat plate part at a spacing narrower than the distance between the compatible walls of annular body A, so as to be rotatably fitted into the annular opening of said annular body A. An annular standing wall is provided, and an annular opening is formed between the compatible walls toward the opposite side of the flat plate part, and gaps are left between the compatible wall and the compatible wall at at least three places in the annular opening around the entire circumference of the flat plate part, and the tip is connected to the compatible wall. A ring body B made of a synthetic resin is provided with a sliding protrusion projecting from the ring body B, and the side wall of the compatible wall is provided with an annular edge portion around the entire circumference that can be locked with the protrusion of the locking piece of the ring body A. A rotation support device in which both the ring bodies are rotatably fitted with the sliding protrusion of the ring body B in contact with the flat plate portion in the opening of the ring body A. (2) The rotational support device according to claim 1, which uses a protruding shaft with a hemispherical tip as the sliding protrusion.
