Abstract
PURPOSE:To enable weight reduction of a micro-shaft by applying a re-drawing work to a metal plate material to form it in a thin long cylindrical body having a bottom. CONSTITUTION:A re-drawing work is applied to a plate material such as a stainless steel plate, etc., by a transfer press machine to form a micro-shaft 1 comprising a thin long cylindrical body having a bottom 6. Thus, since the micro-shaft 1 is made hollow, reduction of weight by 1/4-1/5 can be contrived compared with the micro-shaft made of thin material. Further, the material is hardened by the re-drawing work so that strength and hardness of the micro- shaft are increased.
