次、チップの傾斜を形成し最後にはボールを抱持する端
縁を構成しているものである。(Prior Art) Usually, the tip of a ballpoint pen holds a rotating ball at its tip and has a guide hole for guiding ink contained in the shaft in the ball. The ink to be sent is stored on the bottom surface of the ball and must be guided outward as the ball is rotated for writing. Therefore, conventionally, various holding means or a crimping means of the tip for determining the ball bottom space have been used. It was devised, for example, by arranging multiple rollers, each time when crimping, the roller surface with the required angle is used to sequentially form the inclination of the chip and finally the edge for holding the ball. It is a constituent.

となる欠点がある。(Problems to be solved by the invention) However, when caulking is performed by the plurality of rollers, eccentricity occurs unless the axis of the chip and the center line of the roller rotation axis are accurately determined each time, and the ball bottom portion in the chip is generated. Since the space and the gap seen from the ball center of the holding part can be widened, there is a possibility that the amount of ink outflow will be somewhat, resulting in light and shade of letters, blurring, and leakage of ink. There is a drawback that it becomes difficult and eventually increases the cost.
そこで、この発明は上記従来のものを改良するものであ
