Claims

[Scope of utility model registration request]

a mounting base that is placed on the fabric foundation at an intermediate position between pillars that stand side by side on the fabric foundation; a pair of lower links that have one end pivotally supported by the attachment base and open in an inverted H-shape toward the pillar; an upper link whose one end is pivotally supported by the other end of the link, which intersect with each other and whose intersection portion is pivoted; and a guide fitting that is movably guided by the pillar and supports a frame member installed between the pillars. , a joint fitting that connects the guide fitting and the other end of the upper link and can absorb the displacement of the upper end of the upper link from the column due to the tilting of the upper link by expansion and contraction; A device for lifting a frame member, which is provided with an extendable tool that tilts the frame member in the upright direction and lifts the frame member via a guide fitting along with the tilting.
