PROBLEM TO BE SOLVED: To provide a stepladder fitted with an adjusting base so as to enable a quick response to a wobble in a fixing base by easily adjusting the wobble because the stepladder is unstable and dangerous due to the wobble caused by the unevenness, step height, etc., of a place for setting up the stepladder for the reason that the fixing bases are conventionally installed at four places, on a lower side, of the stepladder. SOLUTION: Characteristically, the fixing base (2) located on the lower side of the stepladder (1) is changed, and the adjusting base (5), wherein a slide piece (3) with an incline can be moved by a screw (4), is provided so as to eliminate the wobble and make the stepladder (1) safe.
