    • A planetary gear reduction system has a sun gear, a plurality of planet gears, a ring gear, and a planet carrier. The planet carrier has a first plate supporting one ends of planet shafts supporting the planet gears, a second plate supporting the other ends of the planet shafts, and a cylindrical drum connecting the first and second plates. The first plate has first portions supporting the one ends of the planet shafts; second portions connecting the first plate to the drum, the first and second portions being provided alternately in a circumferential direction; first cutouts each defined between the neighboring first and second portions, the first cutouts each extending radially inwardly from a circumferential edge thereof to a position adjacent a circle passing centers of the planet shafts; and second cutouts each defined radially inward of the second portion and between the neighboring two first portions, the second cutouts each extending radially inwardly from a first region outside the circle and a second region inside the circle.
    • 行星齿轮减速系统具有太阳齿轮,多个行星齿轮,环形齿轮和行星架。 行星架具有支撑支撑行星齿轮的行星轴的一端的第一板,支撑行星轴的另一端的第二板以及连接第一和第二板的圆筒形滚筒。 第一板具有支撑行星轴的一端的第一部分; 将第一板连接到滚筒的第二部分,第一和第二部分沿圆周方向交替设置; 每个限定在相邻的第一和第二部分之间的第一切口,第一切口各自从其圆周边缘径向向内延伸到与通过行星轴的中心的圆相邻的位置; 以及第二切口,每个切口限定在所述第二部分的径向内侧和相邻的两个第一部分之间,所述第二切口各自从所述圆周外的第一区域径向向内延伸,以及在所述圆内部的第二区域。

    • A lens unit includes a lens holder of stainless steel and a converging lens fixed to a lens holding hole of the lens holder. The lens holder is formed by pressing, or stamping from a metal plate, made of a compressed stainless steel plate material, having a predetermined thickness with a narrow tolerance. Upon stamping, the metal plate is fractured, thus forming an outer tapered surface at one end of the outer surface of the lens holder. When the outer surface and the rear end surface of the lens holder are allowed to abut against a positioning recess in order to position the lens holder, the outer tapered surface is opposed to the corner of the positioning recess.
    • 透镜单元包括不锈钢镜片保持器和固定到透镜保持器的透镜保持孔的会聚透镜。 透镜保持器通过由具有窄公差的预定厚度的由压缩不锈钢板材料制成的金属板进行冲压或冲压而形成。 在冲压时,金属板断裂,从而在透镜保持器的外表面的一端形成外锥形表面。 为了定位透镜保持架,允许透镜保持架的外表面和后端表面抵靠定位凹槽,外锥形表面与定位凹槽的角相对。
