合装置。 A bearing cylinder fitted to the upper part of the leg cylinder, a rotating shaft vertically installed on the lower surface of the seat plate and rotatably passing through the bearing cylinder, and a chrysanthemum-shaped shaft fixed to the lower end of the rotating shaft directly below the bearing cylinder. , each protrusion is inclined outwardly and upwardly just below the rotation axis, and the tip of each protrusion is
The chrysanthemum-shaped washer is located on a circumference with a larger diameter than the rotating shaft, and the base end is also located on a circumference with a smaller diameter than the rotating shaft, and the rotating shaft with the chrysanthemum washer attached is forced into the bearing sleeve. By pushing it in, each protruding piece of the chrysanthemum washer is elastically bent upward, passes through the bushing, elastically restores itself downward, and engages with the bushing. A device for connecting a seat and a leg in a rotating chair, in which the elasticity and rigidity of the chrysanthemum washer are determined so that the rotating shaft does not come off and the rotating shaft can be pulled out by elastically bending each projecting piece outward and downward. .
