To provide a flap table which makes exhibits an appropriate flap function by functioning a torsion bar effectively even when a top plate is large-sized or the like.

In the top plate 2, a spindle m1 to be the center of the flap operation is set near the center C of a top plate depth direction Y orthogonal to the spindle m1, the torsion bar 4 is disposed at a position at which the spindle m1 and an axis match, the side of one end 41 is fixed to a leg body 1 supporting the top plate 2, the side of the other end 42 is fixed to the top plate 2, and the top plate 2 is rotated near the center C of the top plate depth direction Y.
