[Problems to be solved by the invention]
  Generally, the door inner panel in the above-described front door is formed with an opening for attaching the door module unit, and the door module unit is attached to the opening.
[0005]
  The door module unit described above is a module in which door functional parts such as a speaker, a wire harness, a window regulator, and a door latch unit are integrated into a module on a module panel (which agrees with a door module and a module plate).
[0006]
  Conventionally, door function parts such as a window regulator and a door latch unit have been integrated into a module panel in advance so that there are the following problems.
[0007]
  In other words, the door latch unit is connected to the inner handle via a wire cable, and this inner handle is located at a relatively higher position than the door latch position of the door, so when the door latch unit is integrated with the module panel in advance, Assemblability deteriorates.
[0008]
  In addition, the door latch unit described above must be connected to the outer handle via a door key cylinder rod or the like. When the door latch unit is assembled to the module panel first, an operator puts a hand in the door. The operation | work which connects a door latch unit and a key cylinder with a door key cylinder rod is needed, and this workability | operativity deteriorates.
[0009]
  In order to solve such problems, for example, it is conceivable that the door latch unit is assembled on the door side in advance, and then the door module unit is attached. In this case, the door latch and the door latch are attached. Due to the structure of the door latch unit consisting of the actuator that drives the actuator, when the actuator is cantilevered and the door module unit is disposed in the opening for installing the door module, the actuator is located between the door inner panel and the door outer panel. Not only does it escape to the space, but also when the connector on the distal end side of the wire harness that transmits and supplies drive power and drive signal to the connector of the actuator is inserted, the actuator also escapes into the space. There was a problem that smooth assembly was hindered.
[0010]
  The present invention provides an opening for mounting a door module.Mouth rimCombined with door module unitDoor latch unit comprising a door latch and an actuator for driving the door latchThere is a locking part to temporarily depositThe door latch unit is configured such that the door latch unit can be locked on the locking portion.In a door configuration where it is difficult to assemble the door module unit and the door module unit at the same time, it is possible to ensure door assembly.The door latch unit can be secured in a stable state that does not fluctuate in the vehicle width direction, and the door can be easily assembled.It aims at providing the side door structure of vehicles.
[0011]
  The invention also providesA locking portion for temporarily depositing a door latch unit including a door latch coupled to the door module unit and an actuator for driving the door latch is provided at a lip of the opening for mounting the door module, and the door latch unit is provided in the locking portion. Door latch unitTentatively deposit the nextDoor latch unitBy connecting the signal wire to the door inner panel and then fixing the door module unit to the door inner panel,Door latch unitCan be secured in a door configuration where it is difficult to assemble the door module unit body and the door module unit at the same time.The door latch unit can be secured in a stable state that does not fluctuate in the vehicle width direction, and the door can be easily assembled.An object is to provide a method for assembling a side door of a vehicle.
