PROBLEM TO BE SOLVED: To extend a leg part even if it is not a stepladder manufactured in a set, enhance strength, and remove the stepladder from the leg part. SOLUTION: A restricting member 14 is arranged in an end part of a main body 13 so as to sandwich a leg part 2A between the restricting member and the main body 13. A support member 15 is arranged so as to support the leg part 2A by sandwiching the leg part 2A in a width wider than a width of the leg part 2A between the support member and the main body 13 on the same side as the restricting member 14. The main body 13 has a female screw hole 17 in a position opposed to the support member 15. A fixing member 12 has a male screw part 12b threadedly engageable with the female screw hole 17. The fixing member 12 can be fixed in a state of pressing the leg part 2A to the support member 15 by the male screw part 12b.
