    • A pointing device includes an operating body 200 in which one end operably protrudes from an opening 111a of a cover portion 111 of a case body 100 and which is movable depending on the operation toward a horizontal direction from an origin position α; a first returning assisting plate 510 provided with the operating body 200 and having a reception hole 511 penetrating in the thickness direction; a first biasing means 530 which retains the operating body 200 at the origin position α by biasing an outer circumference surface of the first returning assisting plate 510; a fitting block 540 accommodated movably in and out of the reception hole 511; and a second biasing means 550 which biases the fitting block 540 toward the cover portion 111. The fitting block 540 protrudes from the reception hole 511 to fit into the opening 111a of the cover portion 111 by being biased with the second biasing means 550 when the operating body 200 is located at the origin position α.
    • 指示装置包括操作体200,其中一端从壳体100的盖部111的开口111a可操作地突出,并且其可以根据从原点位置α向水平方向的操作而移动; 第一返回辅助板510设置有操作体200并且具有沿厚度方向穿透的接收孔511; 第一偏置装置530,其通过偏置第一返回辅助板510的外周表面而将操作体200保持在原点位置α; 可移动地容纳在接收孔511中的装配块540; 以及第二偏置装置550,其将装配块540偏压到盖部分111.装配块540从接收孔511突出以通过与第二偏压装置550偏压而装配到盖部分111的开口111a中 操作体200位于原点位置α。
