PROBLEM TO BE SOLVED: To easily change only a consumed fore end tip (a fore end portion of a soldering iron tip), and to ensure the optimum working temperature at low cost by minimizing the temperature change of the fore end tip.SOLUTION: A fore end tip for a soldering iron includes: a fore end tip body (14) in which a cylindrical heat accumulation part (14a) of the predetermined wall thickness having a hole (12) with a bar-shaped soldering iron body (6) being inserted therein and freely fitted thereto, and a tip part (14b) to be contracted from a fore end of the heat accumulation part like a pen tip are integrated with each other, and a screw through hole (16) is formed in a side face of the heat accumulation part; a set screw (18) which is screwed in the screw hole in the fore end tip body to urge and fix the soldering iron body inserted in the hole of the heat accumulation part from a side to the fore end tip body; and a stopper body (22) which is fitted to the heat accumulation part so as to cover a rear end of the fore end tip body, and projected from a rear end side of the heat accumulation part to form an internal space to be communicated with the hole, and holds the soldering iron body inserted in the internal space. |
