    • PURPOSE: To prevent a rod part from getting into the peripheral edge end part of an ink outflow gap in assembling. CONSTITUTION: An inward fore end edge part 21 is provided in the fore end of a tip main body 2 made of metal. A plurality of inward projecting parts 22 are provided inside the tip main body 2 in the rear of the fore end edge part 21 by inward pressing deformation. A ball 3 is held rotatably between the fore end edge part 21 and the inward projecting parts 22. The ink outflow gap 4 extending outward diametrically and radially from the central part is formed among the inward projecting parts 22. The rod part 51 urging the ball 3 forward and bringing it into close contact with the inner surface of the front end edge part 21 is inserted through the ink outflow gap 4. The diameter of an imaginary inscribed circle of the central part of the ink outflow gap 4 is set to be larger than the outside diameter of the rod part 51. The minimum dimension of the ink outflow gap 4 is set to be smaller than the outside diameter of the rod part 51.
    • 目的:防止在组装过程中一个杆部件进入墨水流出间隙的周边端部。 构成:内侧的前端缘部21设置在金属制的末端主体2的前端。 通过向内挤压变形,在前端缘部21的后方的前端主体2的内侧设置有多个向内突出部22。 球3可旋转地保持在前端缘部21和向内突出部22之间。在向内突出部22之间形成有从中心部径向径向延伸的墨水流出间隙4.杆部51推动球 3向前方并使其与前端缘部21的内表面紧密接触插入墨水流出间隙4.墨水流出间隙4的中心部分的假想内接圆的直径设定为较大 油墨流出间隙4的最小尺寸被设定为小于杆部51的外径。

    • PURPOSE: To suppress a manufacturing cost to a low value by eliminating necessity of mounting another member for stopping a spring and reducing a labor hour of an assembling work and a number of components. CONSTITUTION: A ballpoint pen comprises the spring 5 disposed in a tip body 2 and a holder 3 to press a ball 23 forward. The spring 5 has a straight part 6 and a coil part 7. The straight part 6 is inserted into the body 2, and the coil part 7 is disposed in the holder 3. A protrusion 4 is integrally provided with an inner surface of the holder 3. The spring 5 rides over the protrusion 4 and the coil 7 to lock the spring.
    • 目的:通过消除安装用于停止弹簧的其他构件和减少组装工作的劳动时间以及多个部件的必要性,将制造成本降低到低值。 构成:圆珠笔包括设置在尖端体2中的弹簧5和向前按压球23的保持器3。 弹簧5具有直线部分6和线圈部分7.直线部分6插入主体2中,并且线圈部分7设置在保持器3中。突起4一体地设置有保持器的内表面 弹簧5越过突起4和线圈7以锁定弹簧。
