Claims (1)

[Scope of utility model registration request] The upper ends of each leg, which is approximately the same shape and size, are hinged to form a ladder shape with a large number of horizontal bars for footrests placed at intervals between two pillars, and can be opened and closed freely. several stepladders as scaffold bodies each having a top plate attached to the top plate, and the several stepladders arranged and erected in a row along the leg opening direction and at intervals, and suspended over the top plate of each stepladder. A footboard to be placed and fixed, and a distance longer than the distance from the front pillar of the first stepladder to the rear pillar of the last stepladder in the several stepladders arranged and erected in a row, and Each of the straight pipes attached to each of the pillars on both sides is fixed to one of the pillars of each of the plurality of stepladders, so that the mutual positional relationship of the plurality of stepladders is immovable. The shaft is provided with a shaft that protrudes from a fixing ring body for rotatably supporting the fixing ring body on the pipe, and is also used for regulating the leg spacing of each of the several legs themselves. A plurality of stepladder spacing regulating members are each attached to the shafts, and are fixed to the other leg post of each of the several stepladders, so that the legs of each of the plurality of stepladders are attached together with the stepladder spacing regulating members. A number that is rotatably attached to a fixing ring for setting the spacing to a desired distance, has a fixing device to the pipe, and is equipped with a short sliding pipe that is slidably fitted onto the pipe. The sliding short pipes of the leg spacing regulating members are respectively fitted onto the pipes, and wheel support holding rods that rotatably hold the wheel supports that support the wheels for transportation are fixed at two locations, upper and lower. each separate stepladder constituted by several leg rings each having a leg ring body capable of bearing thereon, each fixed to said pipe at the upper end of said leg ring body at intervals; A mobile scaffold with wheels, characterized by comprising a stay pipe with wheels for connection.
