To obtain a strong fixing state in a fixing device for fixing a leg body foldably attached in an extended state onto the back side of a top plate by a hinge.
In the foldable leg fixing device 21 rockably holding a pressure plate 31 to press a lateral beam 13a set between leg bodies 13 toward a top plate 12 direction, an engaging part 34 which engages with the lateral beam 13a in a state the leg bodies 13 are extended to hold down the lateral beam 13a is formed on a play end part of the pressure plate 31. Between the engaging part 34 and a site opposing the engaging part 34 in the lateral beam 13a, a fitting hole 35 and a fitting projection 36 as positioning fitting structures to mutually fit together when the leg bodies 13 are extended and to prevent positions from deviatiing in the longitudinal and lateral directions of the lateral beam 13a are formed.
