摘要： PROBLEM TO BE SOLVED: To secure a sufficient reverse rotation resistance by employing an inexpensive material for a worm wheel even if its strength is low without requiring an additional working process and an additional mechanism or component.
SOLUTION: A motor part and a reduction gear part formed by accommodating in a gear case a metal worm connected to a motor shaft of the motor part and a worm wheel meshed with the worm, are integrally assembled. When the motor shaft rotates, the rotation leads to the reduced rotation of the worm wheel through the medium of a metal worm, thereby driving an external output shaft coupled to the worm wheel. The metal worm is finished by form rolling only. The worm wheel is formed by molding polyacetal taken as its material. The advancement angle of the worm gear falls between 3° and 3°30".

摘要翻译：要解决的问题：为了通过使用便宜的用于蜗轮的材料来确保足够的反向旋转阻力，即使其强度低，而不需要额外的工作过程和附加机构或部件。解决方案：通过在齿轮箱中容纳连接到电动机部件的电动机轴的金属蜗杆和与蜗杆啮合的蜗轮而形成的电动机部件和减速齿轮部件被一体地组装。当电动机轴旋转时，旋转导致蜗轮通过金属蜗杆的介质的旋转减小，从而驱动耦合到蜗轮的外部输出轴。金属蜗杆只能通过滚动来完成。蜗轮通过模制作为其材料的聚缩醛形成。蜗轮的推进角度在3°和3°30“之间。版权所有（C）2006，JPO＆NCIPI
