    • Motor-driven movement for timepieces wherein stator block core is formed in ring-shape with a magnetic material of a rounded bar, magnetic poles formed at both core ends are disposed as directed radially inward of the core and rotary shaft of minute hand wheel of output gear train meshing with a rotor disposed between the poles is radially displaced from the center of the core to the side opposite the magnetic poles, whereby internal space of the ring-shaped core having a coil wound thereon is efficiently utilized for arranging all internal components substantially within dimensions of the coil and minimizing the entire size of the movement.
    • 用于钟表的电动机构,其中定子块芯与圆棒的磁性材料形成环形,两个芯部端部形成的磁极沿径向向内设置在输出的分针轮的芯部和旋转轴上 与设置在极之间的转子啮合的齿轮系从芯的中心径向偏移到与磁极相反的一侧,由此有效地利用缠绕有线圈的环形铁芯的内部空间,以将所有内部组件基本上布置 在线圈的尺寸内并使运动的整体尺寸最小化。

    • A flanged coupling member is provided with a shaft portion to which a drive force is input, and a flange portion formed in one end of the shaft portion. The flanged coupling member is coupled to a front housing member with a bolt in which a shaft portion thereof is coaxially arranged in a front housing member and a flange portion contacts an outer surface in an axial direction of a bottom portion of the front housing member. The flange portion is provided with a tubular engagement portion that extends in an axial direction from an outer peripheral edge thereof. The engagement portion is arranged on an outer circumference of the front housing member on the basis of the fastening, and the engagement portion and the front housing member are engaged via a spline. The flanged coupling member is fastened to the front housing member at the shaft portion.
    • 法兰连接构件设置有输入驱动力的轴部和形成在轴部的一端的凸缘部。 凸缘联接构件与具有螺栓的前壳体联接,其中轴部同轴地布置在前壳体构件中,并且凸缘部分接触前壳体构件的底部的轴向方向上的外表面。 凸缘部设置有从其外周缘沿轴向延伸的管状接合部。 基于紧固件,接合部分布置在前壳体构件的外圆周上,并且接合部分和前壳体构件通过花键接合。 凸缘联接构件在轴部分处固定到前壳体构件。
