Abstract
The present disclosure relates to a stepless brake device of a vehicle seat. The coupling piece formed on the plate cover disposed on the outermost rear surface is caulked and coupled to the housing cover disposed on the outermost front side. Therefore, the components are firmly coupled, and no axial gap occurs between the components. Also, tolerance accumulation of the components does not occur, so that the tilt of the roller is reduced, and thus, collision noise of the roller during the release operation is prevented.
