In addition, the tubular fixing block 110 may further include a partition groove 114 ( FIG. 2 ) disposed at equal intervals in the axial direction on the lower circumferential surface and a cutout 115 , in which a part of the circumferential surface is cut off ( FIG. 2 ). .

The aforementioned slot 111 can specify the rotation angle of the chair 2 by designing the length of the slot formed on the circumferential surface of the tubular fixing block 110 in advance.

In other words, the position where the chair 2 is stored under the table 1 and the good position to sit on the chair 2 when the chair 2 is taken out from under the table 1 are located on the circumferential surface of the tubular fixing block 110 . It is set by the length of the spiral shape of the provided slot (111).

The aforementioned elevating block 120 is coupled to be slidable in its axial direction within the aforementioned tubular fixing block 110, and a coupling hole 122 to which the connecting member 30 is coupled to the upper surface thereof (122, FIG. 3) and, Shaft 112 (FIG. 2), each of which both ends are positioned in the aforementioned slot 111, and a rectangular shaft hole 123 (FIG. 2) to which the rotation shaft 141 of the shock alleviation device 142 to be described later is coupled to the bottom surface include
