 In order to achieve the above object, a feature of the present invention is that the chair is a Japanese-style chair, and the chair comprises a base and a sitting body, and a plurality of receiving seats are provided on one surface of the base along the outer peripheral edge of the circumference. A rotating member is arranged on each of the receiving seats, the seat body is formed in an L-shape, a seat portion and a back support portion are wrapped around the seat body with a cloth or a sheet. Then, a fixed frame body is fixed to the bottom of the sitting body, and a storage tank is formed at a position corresponding to the position of the rotating member, whereby the rotating operation of the rotating member in the storage tank is performed. The movement should allow the seat to pivot at least 360 degrees.

Another feature of the present invention is that a turning mechanism is provided at an intermediate portion between the base and the sitting body, which is provided with a cover piece at an intermediate portion between the base and the sitting body, and a half is provided at the cover piece. It is formed so as to surround an arc-shaped storage tank, a plurality of rotating members are stored here, and a bolt is penetrated through the base and both cover pieces, and is finally fixed to a sitting body, and the two cover pieces are joined together. The base and the seat are locked together so as to be integrated, and in this case, the whole chair is smoothly swiveled by the holding and swiveling functions of the swivel mechanism at the intermediate portion. You.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a chair swiveling mechanism. As shown in FIGS. 2 and 3, a case of a Japanese-style room chair 10 having no legs in this embodiment will be described. . The Japanese-style chair 10 includes a base 1, a sitting body 2, and a turning mechanism. Of these, the base 1 is formed in a disk, and a plurality of receiving seats 11 are provided on one surface of the base 1 along the outer peripheral edge of the circumference. Each of the receiving seats 11 is formed in a concave arc shape, and a turning member 3 as a turning mechanism is arranged in each of the receiving seats 111. In the case of the present embodiment, the turning members 3 are rolled. It is a ball, and the rotating member 3 can freely rotate in the receiving seat 11, and a part thereof is exposed to the outside.

The sitting body 2 has an L-shape, has a sitting portion 21 and a back support portion 22, and a connection point between the sitting portion 21 and the back support portion 22 is connected by an active pivoting means 23, and the back support portion is provided. 22 can be adjusted, a cloth 24 or a sheet (see FIG. 4) is wrapped in the sitting body 2, a fixed frame 25 is fixed to the bottom of the sitting 2, and the fixed frame 25 is circular. A storage tank 251 is formed at a position corresponding to the position of the rotating member 3, and the rotating member 3 can rotate the sitting body 2 at least 360 degrees by the rotating action of the storing tank 251.

As shown in FIGS. 2 and 3, in the present invention, another turning mechanism is disposed at an intermediate portion between the base 1 and the sitting body 2. 13 and 26 are provided, and the semicircular arc-shaped storage tanks 131 and 261 are formed so as to surround the cover pieces 13 and 26, and a plurality of rotating members 3 ′ are interposed between the two storage tanks 131 and 261. .

As shown in FIG. 4, when the present invention is assembled, the bolts 4 are passed through the base 1 and the two cover pieces 13 and 26 respectively, and finally screwed to the net of the seat body 2 when assembled. In this case, the two cover pieces 13 and 26 can be screwed together. At the same time, the base 1 and the sitting body 2 can be integrally connected. At the time of use, the rotating members 3 and 3 ′ provided outside and in the middle of the base 1 and the sitting body 2 are rotated in the storage tanks 251, 131 and 261 by the turning mechanism, and the sitting body 2 is attached to the base 1. On the other hand, it can turn at least 360 degrees.
