The invention discloses a damping structure for a seat armrest. The damping structure comprises a driving shaft, a fixing plate and a damping spring, a first clamping part is arranged on the fixing plate, a through hole is formed in the middle of the damping spring, at least one second clamping part is arranged on the peripheral face or the end face of the damping spring, an opening is formed in the axial direction of the damping spring, and the damping spring forms a first free end and a second free end in the opening; the driving shaft is tightly matched with the through hole, and the second clamping part is embedded into the first clamping part to limit the rotation of the damping spring; The invention further discloses the seat armrest which comprises the damping structure, an inner hole of the damping spring is tightly matched with the cylindrical face of the driving shaft to achieve damping, the damping spring is fixed to a clamping opening of the fixing plate through a clamping point, and when the driving shaft rotates, continuous and stable damping torque is generated through friction between the driving shaft and the damping spring.
