ABSTRACT:
A tip for a ball point pen utilizing a water soluble ink is provided, and comprises a ball holder which rotatably supports a ball in a tip end thereof, a ball abutment defined within the ball holder, and an ink passageway providing a communication between the ball abutment and an ink supply path. The ink passage is elongate in cross section. The ball abutment is defined by four flat bearing surfaces which are inclined toward the center of the passageway, two of the bearing surfaces being disposed on each side of the passageway and being directly joined with each other with an angle therebetween, the ball being supported by contact with a point on each of the four bearing surfaces, the joining portions between the bearing surfaces defining an ink reservoir which communicates with the passageway.
