    • PROBLEM TO BE SOLVED: To provide a rocking operation type electrical component capable of securing mechanical strength of an operating knob while preventing liquid from infiltrating in it, and excellent in design. SOLUTION: A through hole 11b is formed in the wall parts 11a facing each other in a mounting frame part 11 protrusively provided in an upper case 1, a pair of rotary shafts 8b protruding face to face are formed on the inner wall part of an operating knob 8, and each rotary shaft 8b is pivotally mounted by inserting it in each through hole 11b from the outside of the mounting frame part 11. Thereby, the operating knob 8 is axially supported by the wall part 11a with the operating knob covering the mounting frame part 11. In addition, a taper part 8c is formed on the side wall 8a of the operating knob 8 so that the operating knob 8 can be surely snapped-in the wall part 11a even if the interval between a partition wall 12 and the wall part 11a in its vicinity is narrowly set, and the interval between the partition wall 12 and the side wall 8a facing the partition wall 12 is slightly widened only on the tip side of the taper part 8c.

    • 要解决的问题:提供一种能够确保操作旋钮的机械强度,同时防止液体渗入其中并且设计优异的摇摆操作型电气部件。 解决方案:在突出设置在上壳体1中的安装框架部分11中的彼此面对的壁部11a中形成有通孔11b,在内壁部分上形成有一对突出的一对旋转轴8b 的操作旋钮8,并且每个旋转轴8b通过将其从安装框架部分11的外部插入每个通孔11b中来枢转地安装。由此,操作旋钮8由操作旋钮 覆盖安装框架部分11.此外,在操作旋钮8的侧壁8a上形成有锥形部分8c,使得操作旋钮8可以可靠地卡在壁部分11a中,即使分隔壁 12和壁部11a在其附近被狭窄地设置,并且分隔壁12和面向分隔壁12的侧壁8a之间的间隔仅在锥形部分8c的顶端侧稍微变宽。 版权所有(C)2006,JPO&NCIPI
