PROBLEM TO BE SOLVED: To compose a load support stand having different right and left lateral widths by utilizing a common stand component member, and eliminate the need for preparing a molding die for molding the whole of the load support stand for each size. SOLUTION: The inner side adjacent to respective stand component members 20A to 21 each other is formed in comb shapes, a support frame material 22 laid between stand component members 20A, 20B at both right and left ends are internally fitted in holes for frame material 35a to 37e provided on respective stand component members 20A to 21, a saw blade shape tooth row 41 for checking is provided on one side comb shaped sides 23, 24 fitted with each other of respective stand component members 20A to 21 along the right and left relative moving direction. A movable piece 42 for checking engaging with the tooth row 41 for checking is provided on the other side comb shaped sides 25, 26 so that an approaching movement of adjacent stand component member is permitted but a separating movement is blocked, and the approaching movement of the stand component members 20A, 20B at both right and left ends is regulated at the both ends of the support frame material 22.
