Abstract
The present disclosure provides a power recliner including a seatback having an angle that is adjusted when an external gear coupled to an accommodation groove of an internal gear is eccentrically rotated as wedges are operated, in which a support groove having a level difference is formed in the accommodation groove of the internal gear and maintains a predetermined radius based on a burring part, in which the wedges are installed and inserted into the support groove so as to be moved along the support groove, and in which when a load is applied to a seatback, the wedges are dually in contact with a cam and an inner stepped surface of the support groove or dually in contact with the burring part of the internal gear and the inner stepped surface of the support groove to disperse the load, thereby improving maximum strength of the recliner.
