The invention aims to provide a motor speed reducer. The motor speed reduction device uses an output gear connected to an output shaft of a motor, a transmission gear engaged with the output gear, a cam integrally formed on the transmission gear, a cycloid inner side gear, and a pair of wedges pressed against an inner diameter portion of the cycloid inner side gear by an elastic restoring force of a spring and tightly attached to the cam. A ring gear engaged with the cycloid inner gear when the cycloid inner gear eccentrically rotates, an end plate that finally outputs the rotational force of the cycloid inner gear, a final output gear, and the like can prevent backlash between the gears when the motor is rotationally driven, so that the seat in a rotationally adjusted state can be easily prevented from moving.
本发明的目的在于提供一种马达减速装置,所述马达减速装置利用连接到马达的输出轴的输出齿轮、与输出齿轮啮合的传递齿轮、一体形成在传递齿轮上的凸轮、摆线内侧齿轮、在通过弹簧的弹性恢复力被按压到摆线内侧齿轮的内径部的同时紧贴在凸轮的一对楔件、在摆线内侧齿轮偏心旋转时啮合的环形齿轮、最终输出摆线内侧齿轮的旋转力的端板以及最终输出齿轮等,可以防止马达旋转驱动时的各齿轮之间的齿隙,因此可以容易防止处于被旋转调整的状态的座椅游动。
