Claims

[Claims for Utility Model Registration] (1) A hollow outer tube 1, an inner tube 2 that is slidably installed inside the outer tube 1, and an inner tube 2 that is provided at the tip of the inner tube 2 on the brush tip side. an elastic gripping member that pinches and releases the writing lead 6; a ring 3 that squeezes the gripping member from the periphery; a holding member that is located closer to the tip of the writing tip than the gripping member and always holds the writing lead 6; It has a spring 4 that applies an elastic force to the inner tube 2 so as to squeeze the gripping member with a ring 3, and each time the inner tube 2 is pressed, the writing lead 6 is held by a predetermined length. In a feeding pencil that is fed out sequentially, a pair of elastic clamp pieces 11 are formed on the outer tube 1 or the tip tube attached to the tip of the outer tube 1 and gradually contract toward the tip side, and each of these clamp pieces A clamp protrusion 13 constituting the holding member is integrally formed at the tip of the inner tube 2, and a pair of elastic protrusions bulges out in a direction substantially perpendicular to the axial direction of the inner tube 2 and constituting the gripping member. A clamp piece 26 is integrally formed at the distal end of the inner tube 2, and a length extending along the axial direction between these bulging clamp pieces 26 exposes the writing lead 6 from the inner tube 2. A feeding pencil characterized in that a hole 25 is formed, and the clamp protrusion 13 is positioned in the elongated hole 25 to hold the writing lead 6. (2) The feeding pencil according to claim 1, wherein the width of the elongated hole 25 is narrower than the width of the clamp protrusion 13 toward the rear end. (3) A writing lead storage body 5 in which a writing lead 6 is stored and communicating with a through hole 22 for the writing lead 6 formed in the inner tube 2 is detachably connected to the inner tube 2. The feeding pencil described in item 1. (4) The inner tube 2 is extended beyond the rear end of the outer tube 1, and a sharpener 8 for sharpening the writing lead 6 is attached to the rear end of the inner tube. Retractable pencil.
