PURPOSE: An in-body of a digital door lock is provided to reduce a failure. CONSTITUTION: A plurality of fixing units(15) and an inner body(20) are combined with insert injection. A plurality of the fixing unit covers synthetic resin in an inside of a synthetic resin body(10) with constant thickness. The inner body forms a penetration hole. A body and the inner body form an inserting unit(21) on the center. The inserting unit rotatably inserts a handle axis(12a) of a handle for opening a door. A first hooking protrusion(22) and a second hooking protrusion(23) are formed in both sides of the inserting unit and support a torsion spring(30) combined in an outside. A stopper(24) is formed in a lower side of the inserting unit and prevents opening of the torsion spring. A rotating plate(40) rotates with the handle by combining the same with the handle axis in an upper side of the inserting unit and returns by elastic force of the torsion spring.
