    • PROBLEM TO BE SOLVED: To simplify a configuration of a drive device for an electric vehicle by reducing the number of components thereof.SOLUTION: Internal teeth 42 of a rotor shaft 24 composing a motor for driving 12 mesh with external teeth 45 of a gear member 44. As a result, the gear member 44 rotates under action of the motor for driving 12. A first tooth part 48 is formed in the gear member 44, and a second tooth part 56 is formed on a side wall of a large diameter part 100 of an outer member 54 composing a constant velocity joint 16. The first tooth part 48 meshes with a third tooth part 58 of a first gear part 62 in a two-stage helical gear 52, and the second tooth part 56 meshes with a fourth tooth part 60 of a second gear part 64 in the two-stage helical gear 52. The diameter of the large diameter part 100 of the outer member 54 is set larger than the second gear part 64.
    • 要解决的问题:通过减少其部件数量来简化用于电动车辆的驱动装置的构造。解决方案:构成用于驱动12目的电动机的转子轴24的内齿42与齿轮构件的外齿45 结果,齿轮构件44在用于驱动的​​电动机12的作用下旋转。第一齿部48形成在齿轮构件44中,第二齿部56形成在大直径部分的侧壁上 构成等速万向节16的外部构件54的第一齿部48与第二齿部52的第四齿部58啮合。第一齿部48与第二齿部62的第二齿部58啮合。 两级螺旋齿轮52中的第二齿轮部64的齿部60.外部构件54的大直径部100的直径设定为大于第二齿轮部64。
