To provide a shaft pressing metal fixture and a metal pipe processing method using it which can press a shaft without causing a buckling to a metal pipe or deforming its end surface.

At a tip end of a shaft pressing metal fixture body 10, a run-away 11 to be inserted inside a metal pipe is formed. A ring-shape shoulder 14 is formed at a connecting part of the body 10 and the run-away 11. In this case, the shoulder 14 is made to be such a shape that a peripheral side of the step is slanted towards a metal pipe side. With a usage of this shaft pressing metal fixture, the shaft can be pressed while the end face of the metal pipe is bound, resulting in an improvement of a moldability.
