    • Axial positions of two driven external gears 66 making up each of a plurality of paired-gear groups 67 with respect to an input shaft 62 are made identical, and a different paired-gear group 67 is arranged by being offset in the axial direction of the input shaft 62. Therefore, only two driven external gears 66 making up the paired-gear group 67 are present at an identical axial position of the input shaft 62. Consequently, even if the diameters of these driven external gears 66 are made large up to the very limit, these driven external gears 66 do not interfere with each other. Accordingly, it is possible to readily enlarge the reduction ratio based on the driving and driven external gears 65 and 66.
    • 构成相对于输入轴62的多个成对齿轮组67中的每一个的两个从动外齿轮66的轴向位置相同,并且不同的成对齿轮组67沿轴向方向偏移 输入轴62.因此,只有两个构成成对齿轮组67的从动外齿轮66存在于输入轴62的相同的轴向位置。因此,即使这些从动外齿轮66的直径大到 这些被驱动的外部齿轮66不是相互干扰的极限。 因此,可以容易地根据驱动和驱动的外齿轮65和66来增大减速比。

    • Each permanent magnet formed in an open-letter shape is divided into a plurality of parts, the divided magnets are respectively fitted in open letter-shaped inserting portions, and ribs are respectively provided in dividing portions of the permanent magnets. Accordingly, it is possible to prevent the breakage of pole connecting portions at an outermost periphery of the rotor as adjacent inner peripheral-side permanent magnets directly come into contact with and push the outer peripheral-side permanent magnets. Alternatively, an annular nonmagnetic material is provided on an outer peripheral portion of the rotor so as to cover the open letter-shaped permanent magnets and magnetic material portions inside the open-letter portions, whereby the rotor core is made resistant against breakage, and the flux leakage is minimized.
    • 形成为开放字形的永磁体被分成多个部分,分割的磁体分别装配在开放字母形的插入部分中,并且在永磁体的分割部分分别设有肋。 因此,可以防止在相邻的内周侧永久磁铁直接与外周侧永久磁铁接触并推动外周侧永久磁铁时,在转子的最外周的极连接部的断线。 或者,在转子的外周部设置环状非磁性材料,以覆盖开放字母部分内的开放字母形状的永久磁铁和磁性材料部分,从而使转子芯抗破坏, 磁通泄漏最小化。
