PROBLEM TO BE SOLVED: To provide an aqueous ball-point pen which enables the normal connec tion of a refill incorporated in a ball-point pen tip to an ink guide refill and the secured smooth ink supply to the incorporated refill from the ink guide refill. SOLUTION: This aqueous ball-point pen is of such a construction that a ball-point pen tip 1 is fixed by a tip retainer 2 and the rear end part of a refill 3 incorporated in the ball-point pen tip 1 is protruded into a hole 5 into which an ink guide relfill 6 is stored by running the rear end part through a through hole 4 in the tip retainer 2 and thus the incorporated refill 3 is caused to connect with the front end part of the ink guide refill 6. In this case, an annular protrusion 8 which protrudes backward encircling the incorporated refill 3 to be introduced into the front end part of the ink guide refill 6, is provided around the through hole 4 in the front end inner wall 7 of the hole 5 in the tip retainer 2. |
