摘要： PROBLEM TO BE SOLVED: To save a mold cost by eliminating a fragile part to a moment, improving durability and a strength, and smoothly supplying an ink. SOLUTION: A needle tip for a writing instrument comprises a cylindrical part 4 formed in a larger inner diameter than the outer diameter of a ball 12, a conical part 6 formed on an oblique surface extended from on tip part of the part 4 and gradually reducing in its diameter, and a ball holding part 8 formed with a plurality of holding protrusions 9 projected from the tip part of the conical part 6 to the inside and rotatably assembled with the ball 12. In this case, the part 6 and the part 4 are integrally formed by spinning. The method for manufacturing it comprises a step of spinning to form the part 4 having an inner diameter larger than the outer diameter of the part 6 and the ball 12, and a step of punching to project the plurality of the protrusions 9 for rotatably assembling the ball at the tip part of the part 6 on the inner periphery.

摘要： A tip mechanism for a knock type ballpoint pen with an ink container (12) includes a tip body (10) having an inner ink-guide hole (15) and top and bottom end portions. The top end portion of the tip body is fitted within the ink container. A ball receptor is formed at the bottom end portion of the tip body. A ball (30) is disposed in the ball receptor to be rotated. The ball (30) is partially exposed to the outside. An elastic member (20) is inserted into the ink-guide hole of the tip body. The elastic member has a ball pressing part (25) for pressing the ball toward the outside. The ball pressing part (25) is formed with a curved shape. The curved shape of the ball pressing part is processed by bending the ball pressing part at a predetermined angle.
