題がある。[Problems to be solved by the invention] However, such a material made of brass lacks rigidity in terms of weight, and there is a possibility that the arm may bend or bend sideways, and since it is cast, the The production is troublesome. Therefore, it is conceivable to manufacture the arm by extrusion molding or welding of a plate body using a light metal such as aluminum. According to this, although the rigidity can be increased in comparison with the weight of the conventional arm, there is a problem that the arm as a whole is large and it is difficult to use as a welding machine.

A steel plate is adhered to the surface of the base body that receives the tensile stress.
［作用］ アーム基体を軽金属の押出成形或は板体の溶着で形成す
