Disclosed is a one-way damping structure, comprising a spring, a drive element and a friction force generation member, the spring and the drive element being connected such that the spring is driven by means of the drive element; the spring comprises a fixing portion, a connecting portion and an annular portion, the connecting portion being located between the fixing portion and the annular portion and connecting the fixing portion to the annular portion, and the fixing portion being fixed; and the annular portion comprises at least half a turn for defining a spring opening which spirally extends in the circumferential direction, and slides relative to the friction force generation member so as to generate friction torque. Also disclosed is an adjusting assembly and a seat height adjuster utilizing one-way damping properties in which the spring of the one-way damping structure generates different torques in different rotation directions.
