The invention relates to a manual angle adjuster and an adjusting method. The manual angle adjuster comprises a center shaft connected with an external power source and a transmission assembly driven by the center shaft, the two sides of the transmission assembly are wrapped with sealing assemblies, and each sealing assembly comprises a fixed disc, a movable disc matched with the fixed disc and a closed ring hooped at the wiring position of the fixed disc and the movable disc. The transmission assembly comprises a cam driven by the center shaft, a mask driven by the cam, a tooth block and a spring installed on the fixing disc. A plurality of stirring teeth are annularly arrayed on the outer circle surface of the cam, the inclination directions of the stirring teeth are the same, the center shaft is coaxially sleeved with the mask, a plurality of containing grooves are formed in the mask, the tooth blocks reciprocate in the containing grooves, and a component is driven in a cavity formed by the mask, the movable disc, the fixed disc and the closed ring. Unlocking, angle adjusting and locking of the seat backrest are achieved, and the backrest can enter an idle stroke area.
