Summary:PROBLEM TO BE SOLVED: To provide a knock-type mechanical pencil that can be inexpensively produced by reducing the assembly manhours along with simplifying a structure due to a reduction of the number of components while increasing the number of leads 8 storable in a lead tank 4 by enlarging the diameter of the lead tank 4. SOLUTION: Circumferentially-extended elastic pieces 1A are formed in a coupling member 1 so that the coupling member 1 is protruded from the tip of a barrel 9 while being inserted from the rear of the barrel 9. The elastic pieces 1A prevent the coupling member 1 from being detached to the rear while being brought into contact with the front end of the barrel 9. COPYRIGHT: (C)2008,JPO&INPIT
