To provide a compact and light pot mount base which can suppress the bending of a top plate.
This pot mount base comprises a top plate 1, a top plate reinforcing member 2 attached to the lower surface of the top plate 1 along the central line of the top plate 1, a pair of support leg connecting members 4 arranged between pairs of support legs 3 disposed both end sides of the top plate reinforcing member 2, a pair of diagonal members 5 diagonally disposed between the pair of support leg connecting members 4 and the top plate reinforcing member 2 and connecting members 6 disposed below the top plate reinforcing member 2 to connect the pair of diagonal members 5 together. Thus, the connecting members 6 are formed so as to be stretched through a turnbucke 7.
