PURPOSE: A multi-damping structure for driving a window lifting motor is provided to reduce the impact induced on a worm gear by operating a multi-damping function of a plurality of spring plates and a buffer disk. CONSTITUTION: A worm gear(400) is provided with saw-teeth on an external surface for coupling to a worm shaft, and a circular side wall(402) on the bottom of a circular disk groove(403) with a first through hole(401). A buffer disk(200) is provided on the disk groove(403) of the worm gear(400), provided with a second through hole(201) on the center of axis, and adhered with a plurality of spring fixing holes(202) at the circumference. A plurality of spring plates(100,110) are coupled to the spring fixing holes(202) of the buffer disk(200) and fixing slits(406) of the worm gear(400) in a way of force fit. A dog plate(300) is provided with drive fins(303) inserted into drive grooves(203) of the buffer disk(200), and a hole(301) for use in a shaft coupling on the center of axis.
