As shown in FIG. 9 and FIG. 9, a mounting plate (26) is formed which is in contact with the lower surface of the seat (1) and has a mounting hole (25) such as a bolt,
On its lower surface, a spacer (27) sandwiched between the stays (3a), (3b) and an outer frame fitted around the stays (3a), (3b).
It has (28). The mounting plate (26) is provided so that the back is lowered in the case of the seat (1) having a backrest, and is provided in the horizontal state in the case of the top plate (2) and the like. The outer frame may be fitted only on the outer circumference of one of the stays, but in the figure, it is formed in a generally U-shaped or C-shaped cross-section that opens downward, and the end piece (29
The stays (3a) and (3b) are fitted into the stays (3a) and (3b), respectively. A nut (30) is welded to one end piece (29a), and the receiving groove (32) of the bolt (31) engaging with the nut (30) is welded to the other end piece (29b). ) Has been formed. Further, although the spacer (27) projects to the upper surface of the mounting plate (26) and is welded at the projecting portion, the entire support frame including the outer frame may be integrally molded. The spacer (27) has the outer frame (2
A guide groove (33) for receiving the bolt (31) is formed so as to extend downward more than 8).
