<P>PROBLEM TO BE SOLVED: To prevent a gate mark from standing out, to protect the beautiful appearance of a casing, to prevent the movement of a refill from being hindered even when the gate mark is protruded, and to enough control the shake of a pen point during writing. <P>SOLUTION: The refill of a writing implement is housed in the casing 2. A tip opening 3 through which the pen point 5 of the refill passes is formed in the tip part 21 of the casing. The tip part 21 of the casing 2 is formed at least by the injection molding of a synthetic resin. A recessed part 31 is formed in a part of the opening end part of the inside surface of the tip opening 3. A gate part 32 for injection molding is formed in the recessed part 31. A support part 33 for supporting the outside surface of the refill (the front part 61 of a pen point holder) is formed in a part excluding the recessed part 31 of the opening end part of the inside surface of the tip opening 3. <P>COPYRIGHT: (C)2003,JPO |
