It consists of a lead guide pipe that is biased forward in the axial direction by a spring, and a lead holding device that is built into the shaft cylinder and can hold the lead reliably in the direction of retraction with little resistance in the direction of feeding out the lead. , an automatic feeding type sharp pencil in which the lead guide pipe retreats as the lead wears out to allow writing, and when the lead guide pipe moves forward in the axial direction, the lead is fed out following the lead guide pipe. A tightening ring is loosely fitted to the sliding body fixed to the pipe or the core guide pipe so as to be able to slide as appropriate, and an elastic part that can be expanded by the pressure of the tightening ring is formed on the inner shaft fixed to the shaft cylinder, The elastic portion;
A protrusion is formed on either the outer side of the core guide pipe or the sliding body, and a serrated engagement part is formed on the other side, and when the serrated engagement part and the protrusion engage, the core guide pipe becomes axially This is an intermittent movement device for the lead guide pipe of an automatic sharpening pencil that can be moved backward in the axial direction with little resistance, and can be engaged with a strong force in the axial direction forward.
