回転盤１とし、この回転盤に均等間隔廃の貫通穴
をあけて球２を回転可能にはめ込み、上板３と下
板４で球２を挾む形で相対回転する構造に組み付
ける一方、上板３、回転盤１と下板４が各々独立
して回転するため、上板３と下板４に固定した心
棒５を真中より切り離し留板６を取り付ける。軸
受板７の穴は心棒の直径より大きくして隙間を設
けて偏心回転する構造にした回転装置で下板４を
椅子の脚に固定し、座盤とした回転椅子。 The rotating disk 1 is a donut-shaped flat plate with concentric holes in the center, and the rotating disk is made with evenly spaced through holes and the balls 2 are rotatably inserted into the rotating disks. While they are assembled in a structure that allows them to rotate relative to each other in a pinched manner, the upper plate 3, rotary plate 1, and lower plate 4 each rotate independently, so the mandrel 5 fixed to the upper plate 3 and lower plate 4 can be separated from the middle to create a retaining plate. Attach 6. The rotary chair is made by fixing the lower plate 4 to the legs of the chair and using it as a seat using a rotating device which has a structure in which the hole in the bearing plate 7 is larger than the diameter of the mandrel and rotates eccentrically with a gap provided.
