The invention discloses a gap adjusting component which is a plastic piece and comprises a cylinder part with an inner cavity. A first end of the cylinder part is opened, and a second end of the cylinder part is provided with an axial limiting end wall. An axial gap adjusting corrugated edge is arranged at the first end of the cylinder part. The corrugate fluctuating direction of the axial gap adjusting corrugated edge is parallel to the axial direction of the cylinder part. After the gap adjusting component is applied to an electric lifting adjusting device of an automobile seat, the axial gap of an output shaft for driving a motor is eliminated through the deformation of the axial gap adjusting corrugated edge of the gap adjusting component, and the tolerance requirement of a reduction gearbox body and a worm is lowered. The gap adjusting component has the advantage that by means of the gap adjusting component, an adjusting spring, a wear-resistant gasket and an oil-contained bearing in the prior art are replaced to eliminate the axial gap, the number of parts is decreased, assembling is simplified, and cost is reduced. In addition, the gap adjusting component can be designed in a modularized mode.
