Abstract
A feeding pencil includes a main body, a leading tube, a middle tube, and a ratchet mechanism. The middle tube is engaged to the leading tube to be relatively rotatable. A relative rotation between the leading tube and the main body in one direction moves a drawing material forward. The ratchet mechanism allows the relative rotation between the leading tube and the main body in the one direction, and regulates the relative rotation in another direction. The ratchet mechanism includes an elastic projecting part and a concave-convex part. The concave-convex part engages with the elastic projecting part to be movable in an axial direction and rotatable. A protrusion disposed at a center tube removably engages with an annular convex part disposed at an outer surface of the leading tube in the axial direction.
