Abstract: Disclosed herein is an inside door handle assembly in a vehicle may include: a handle bracket in which a lever of the inside door handle is rotatably installed and a hook coupling hole is formed; a coupling protrusion protruding from the handle bracket; a mounting plate protruding from a door module, having a coupling groove into which the coupling protrusion is inserted in a direction parallel to a door, and having a locking bump to support the coupling protrusion such that the coupling protrusion is not moved in a direction crossing the door in a state where the coupling protrusion is inserted into the coupling groove; and a hook formed integrally with the door module so as to protrude from the door module, and inserted and coupled to the hook coupling hole of the handle bracket.

Abstract: Disclosed herein is a door module for a vehicle, which is mounted in a door panel of a vehicle door. The door module may include: a stiffened plate including base plates formed at positions where one or more hardware parts related to the vehicle door are mounted and a connection plate for connecting the base plates, wherein the base plates and the connection plate are integrally formed; and a resin panel covering an opening of the door panel, and formed by over-molding resin onto the stiffened plate, wherein the stiffened plate is formed of a material having higher stiffness than the resin.

Abstract: A wiring harness assembly of a door module, includes: an FPCB (Flexible Printed Circuit Board) connected to an external power supply for supplying electricity to a plurality of electric devices installed on the door module; a cover member coupled to the FPCB while protecting the FPCB; and a rib for protecting the FPCB from water.
