    • An input device comprises a rotatable magnet member, a lower casing and an upper casing. The rotatable magnet member has a magnet, a spherical part and a rod-like shaft. The magnet is formed into a ring-shaped disc with a through hole in the center, and magnetized with N and S poles alternately along the circumferential direction. The rod-like shaft having a flange portion near a first end is inserted in the through hole, and both ends protrude from the through hole. The lower casing rotatably supports the rod-like shaft of the rotatable magnet member. There is a space provided between an outer peripheral surface of a part of the rod-like shaft inside the through hole and an inner wall of the through hole over the entire peripheries, and the flange portion is press-fitted and fixed to the spherical part.
    • 输入装置包括可旋转的磁体构件,下壳体和上壳体。 可旋转磁体构件具有磁体,球形部分和杆状轴。 磁体形成为具有中心的通孔的环形盘,并且沿着圆周方向交替地用N和S极磁化。 具有靠近第一端的凸缘部分的杆状轴插入通孔中,两端从通孔突出。 下壳体可旋转地支撑可旋转磁体构件的杆状轴。 在通孔内部的棒状轴的外周面与整个周边的贯通孔的内壁之间设置有空间,凸缘部被压入并固定在球面部 。
