Reference numeral 14 is a side rod having one end rotatably attached to both sides of the pedestal 1 via support metal fittings 15. Both sides rod 1
The other ends of 4 are connected to each other by a rod 14 'so as to rotate in synchronization with each other.

Further, the backrest 12 is provided with the other end locking metal fitting 16 of the side rod 14 so as to stop the rotation of the backrest 12 which has been rotated to the vertical position. As shown in FIG. 3, the locking metal fitting 16 is provided with a projecting piece 17 attached to the backrest 12, and a notch 18 provided so that the rod 14 ′ is fitted upward from the lower edge of the projecting piece 17. Protrusion 1
7 is attached rotatably to the end via pin 19 and
The hook 20 holds the lower peripheral surface of the rod 14 'in the notch 18 as it rotates in the descending direction, and the operating rod 21 that connects the left and right hooks 20. The hook 20 is rotated clockwise in FIG.
