摘要： PROBLEM TO BE SOLVED: To provide a leg with a length adjusting device, which can easily maintain engagement between a rear edge of an operating plate and a supporting protrusion therefor, without hindering rotation of the rear edge of the operating plate, allows the operator to visually check the engagement from outside and to predict the risk of slipout of the rear edge of the operating plate from the supporting projection during working, and provides excellent safety, and to provide a stepladder. SOLUTION: According to the structure of the leg with the length adjusting device, part of a case rear wall 15 of the length adjusting device 6 is bent and protruded to communicate between the interior of a main body of a case 7 and the interior of an overhung portion 24, and the rear edge 25 of the operating plate 13 housed in the main body of the case 7, is inserted into the overhung portion 24 via a communication port. Then the vicinity of a bent portion from the main body rear wall 15 of the case 7 to an upper wall 26 of the overhung portion 24 is formed into the supporting protrusion 16 abutting on the operating plate 13, and a wall inner surface of the overhung portion 24 is separated from an area where the rear edge 25 of the operating plate 13 moves, followed by forming a checking opening 29 via which the interior is visible, at least in one of right and left surfaces of the overhung portion 24.
