チヤツク。[Scope of Claim for Utility Model Registration] 1. In a chuck configured to removably grip the lead by opening and closing the lead gripping part, a chuck base piece having a groove extending in the longitudinal direction on the inner surface is formed of a synthetic resin material, The concave grooves on both sides of the chuck base piece are directed outward from the center of the chuck base piece to define a lead guide part and a lead grip part, respectively, and when the chuck base piece is bent at the center part, the lower ends of the central cross section are connected. A broken part is formed in the central part so that the cross section of the remaining part is cut, and the chuck base piece is folded so that the lead gripping part and the lead guide part on both sides face each other to form a lead insertion hole to form a chuck. Shape pencil chuck. 2. The sharpening pencil chuck according to claim 1, wherein the synthetic resin material is filled with a filler in the form of short fibers to reinforce the central connecting portion.
