Round gapless angular modulation device for vehicle

Abstract

A round recliner for a vehicle having three lock gears evenly spaced apart from each other. Each of the lock gears are interposed between a cam and a corresponding lock gear supporting member in such a manner that the lock gears are engaged with a circular inner gear part of a sector gear, wherein the lock gears are turned along the lock gear supporting members so that an outer gear part of each of the lock gears is disengaged from the inner gear part of the sector gear or the outer gear part of each of the lock gears is engaged with the inner gear part of the sector gear, thereby minimizing occurrence of clearances in the recliner and preventing any irregular engagement of the recliner.
