摘要:
A feeding pencil includes a pipe member, a leading tube, a tubular main body, a movable body, and a holding member. The pipe member is disposed inside the leading tube and loads a drawing material. The movable body extends in an axial direction includes a male screw formed across an entire outer periphery thereof in the axial direction. The holding member holds the movable body. The pipe member includes a female screw on an inner surface thereof. The female screw screws with the male screw. A relative rotation between the leading tube and the main body relatively rotates the pipe member and the holding member and acts a screwing action between the male screw and the female screw. The screwing action moves the movable body forward to extrude the drawing material from the pipe member.
