Description of the Related Art Conventionally, a ladder used when climbing to a high place such as a roof is made of a pair of two main pillars made of wooden or metal and having a predetermined length. In the case of a wooden ladder, the crosspiece is usually fixed to the main pole by a tenon using a square bar. In addition, a metal-made one is formed by using a C-shaped channel material or a long rectangular cylinder as a main column, and a pair of main columns is provided with a rectangular pipe-shaped step at a regular interval. When using any of them, lean them against an elevating site such as a roof and go up or down as they are. In addition, there is also one made of this metal, which is a double telescopic type, which is a type in which one ladder body is slidably connected to the other ladder body, and is used for lifting sites and the like. Extend one of the ladders according to the height and use it. There is also a stepladder ladder that can be folded from the middle with this metal ladder, and is used as a ladder by being extended and bent to be used as a stepladder.
