摘要： In a fibre-tipped pen with an ink storage body (4), a writing wick (6) and an intermediate storage body (5) arranged between the writing wick (6) and the ink storage body (4), the intermediate storage body (5) is surrounded by a support tube (10) which rests on the pen housing (1). A support body (7) is fixed to the writing wick (6) and rests on the support tube (10), so that the writing pressure is not transmitted to the connection between the rear end of the writing wick (6) and the front end of the intermediate storage body (5).

摘要： PURPOSE: To smoothly separate a tip member and a writing fluid cartridge and easily fit both members in exchanging writing fluid cartridges by fitting an auxiliary tool to a tip member from front and engaging it with an expandable open engaging part in the expanded state. CONSTITUTION: When a tip member 2 is inserted into a writing fluid cartridge 10 from front, an annular shoulder 8 of a radial protrusion of the member 2 contacts the front area obliquely extending to inside the radial direction of a hook-shaped protrusion 12, the protrusion 12 is mutually separated by elastic bending, the shoulder 8 passes through the hook area, and the rear annular face of the shoulder 8 abuts on the front end face of the cartridge 10. Here, the protrusion 12 elastically returns to fix the returned member 2 in the axial direction unmovably. When the protrusion 12 is mutually separated to expand the opening, the shoulder 8 is released from the hooking area of the protrusion 12, and the cartridge 10 can smoothly be drawn out from the tip member 2.
