パイプ間歇移動装置。 A core guide pipe is built into the shaft cylinder so that it can slide freely in the axial direction and is biased forward in the axial direction.The core is moved forward in the axial direction with a small force, but is held in the rear direction with a strong force. The automatic feeding type sharpener consists of a lead holding device that allows the lead guide pipe to retreat as the lead wears out, allowing writing to be performed, and in which the lead is fed out by following the lead guide pipe when the lead guide pipe moves forward in the axial direction. In a pencil, a flat member is constructed by integrally or separately comprising a fastener member having a tapered surface inclined in the axial direction and a flat surface portion extending flat in the axial direction, with the tapered surface and the flat surface portion facing each other. Further, a retainer is attached to the flat member so as to be movable in an appropriate axial direction, and is frictionally connected to the fastener member via an elastic body, and a ball rotatably provided on the retainer is attached to the fastener member. one of the fastener member and the flat member is provided on the core guide pipe, and the other is provided on the shaft cylinder, and the fastener member An intermittent moving device for a lead guide pipe of an automatic mechanical pencil, characterized in that at least one of the flat surface portion and the flat surface portion is configured to be swingable in an axial direction and a direction perpendicular to the axial direction.
