The present invention relates to a novel framework of a door and a drawing device for manufacturing a jamb of the framework which ensure an aesthetic property, improvement of strength and an anti-corrosive property such that replacement is unnecessary. To this end, the present invention comprises: a core forming a framework inside; a center part which is formed in a multi-stage bending shape to surround the surface of the core and is molded with glass fiber as a main material; a mat portion which surrounds the outer surface of the center part and prevents the original pattern of the glass fiber from being seen through to the outside; a jamb which surrounds the outer surface of the mat portion and is composed of a surface portion forming the surface region; and a brick mold which is coupled along the border of the front surface of the jam.
