PROBLEM TO BE SOLVED: To provide a method of manufacturing an interdental brush by which production efficiency is increased and production cost is reduced by stably positioning a brush bar. SOLUTION: The method of manufacturing an interdental brush includes: inserting the brush bar into the through hole of a handle (viz., combining step); pressing then the brush bar exposed in a positioning groove of the handle with a pressing device to form a plurality of extended sections on the positioning groove of the brush bar and, since the maximum outer diameter of the extended sections is in excess of the hole diameter of the through hole, positioning the brush bar stably in the positioning groove in a caught state (viz., positioning step ); and finally performing a molding step for enclosing the brush bar with a filler. On the basis of the foregoing method, the positioning of the brush bar is more stabilized, preventing a shortcoming of the brush bar being detached during the use. COPYRIGHT: (C)2011,JPO&INPIT
