`
`[0005] Furthermore, the door internal panel is combined with a door trim as an internal
`
`material provided with a door switch or window switch, and an impact beam is disposed
`
`close to the door external panel to increase the side impact rigidity of the door.
`
`[0006] However, in the conventional door structure as described above, since the door
`
`internal panel and the door frame are usually made of steel, the weight of the door is
`
`increased.
`
`Since the door internal panel and the door module are separately
`
`manufactured so that the number of parts of the door is increased, it is necessary to
`
`develop a more innovative vehicle door by reducing the number of parts of the door and
`
`reducing the weight of the material.

`
`BRIEF SUMMARY
`
`[0008] Various aspects of the present invention are directed to providing a door of a
`
`vehicle configured for reducing the number of parts of the door by modularizing a large
`
`number of parts forming the door, reducing the weight by making a portion of the door
`
`module including a relatively lightweight material instead of a steel material, and reducing
`
`assembly man hour and cost.
`
`[0009] A door of a vehicle according to an exemplary embodiment of the present
`
`invention may include a first door module forming a door skeleton, a second door module
`
`coupled with the first door module and forming a door window. A reinforcement
`
`member may be inserted along an edge portion forming the door window of the second
`
`door module.
`
`[0010] The first door module may be formed of a metal material, and the second door
`
`module may be formed of a plastic material.
