Production structures having a portion of the tubular structure or tubular 剖位 is conventionally cut has been carried out by a method such as forging or casting, the material yield is low, machining cracking occurs, the shrinkage cavity there has been such a problem arise. The present invention provides a completely new and novel way to replace these methods. In the present invention, using a rotatable tool, in the state in which the annular jig outside the tool is inserted while rotating the tool to the workpiece. Then, the tool and by generating frictional heat between the workpieces cause plastic flow state to the workpiece, the workpiece was a plastic flow state between the tool and the annular jig It is filled in the space to produce a tubular structure with. Cutting, forging or over conventional methods by casting or the like can be produced precision, a tubular structure with excellent quality at a low cost.
