ことを特徴としたノック式シャープペンシル。 ２ 芯管８の内部に漏斗１４を設けた実用新案登録請求
の範囲第１項記載のノック式シャープペンシル。 ３ 芯管８に芯管キャップ１５を設けた実用新案登録請
求の範囲第１項記載のノック式シャープ−ペンシル。[Claims for Utility Model Registration] 1. A lower part 2 of the main body and an upper part 1 of the main body having a vertical groove 9 on the inner periphery are connected to the upper part 1 of the main body via a pivot pipe 3 having a vertical groove 12 on the inner periphery of the upper part. A mechanical pencil main body is formed by connecting the main body lower part 2 so as to be rotatable and removably tightly fitted, and a spiral tube 4 having a convex portion 11 on the lower end side is provided in the main body upper part 1. The convex portion 11 is fitted into the vertical groove 12 of the pivot tube 3 so that it can move up and down, and a core tube 8 is provided in the lower part of the main body so that the vertical movement of the helical tube 4 is linked to the core tube 8. In the spiral tube 4, an eraser receiver 5 is provided which is loosely inserted into the vertical groove 9 of the upper part 1 of the main body and has a convex portion 13 passing through the spiral groove 16 of the spiral tube 4, so that the eraser receiver 5 can be moved up and down. This knock-type mechanical pencil is characterized in that the degree of protrusion of a long eraser 6 provided in an eraser receiver 5 can be adjusted by rotating the upper part 1 of the main body. 2. A knock-type mechanical pencil according to claim 1 of the utility model registration claim, in which a funnel 14 is provided inside the core tube 8. 3. A knock-type mechanical pencil according to claim 1, in which the core tube 8 is provided with a core tube cap 15.
