[0002]

2. Description of the Related Art Conventionally, a door inner panel is provided inside a door outer panel of a vehicle body, and a side beam is provided inside the door outer panel along the front-rear direction of the vehicle body, so that one door inner panel is provided. A door check is provided on the side, a door hinge is provided outside one side of the door inner panel, a door lock is provided inside the other side of the door inner panel, and a periphery of the door inner panel is provided near the periphery of the door outer panel. Fixed car doors are known.

[0003]

However, in a conventional automobile door, since the door inner panel is mounted inside the door outer panel separately from the side beams, the work of mounting the door inner panel to the door outer panel is troublesome. It is troublesome and requires a door check,
Since the door hinge and the door lock are separately mounted on both sides of the door inner panel, the work of installing the door check, the door hinge and the door lock on the door inner panel is also troublesome and troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to address the above-mentioned problems, to be easily assembled, to easily adjust the distance between sashes for guiding both side edges of the window glass according to the width of the window glass, The outer panel is hardly deformed even if it receives a shock from the outside of the vehicle body, and a shock absorber is stored between the door inner panel and the mid panel to make effective use of the space between the door inner panel and the mid panel. It is an object of the present invention to provide a car door which can be designed.

[0005]

A vehicle door according to the present invention has a door inner panel disposed inside a door outer panel of a vehicle body, and is provided inside the door outer panel along a longitudinal direction of the vehicle body. Arrange the side beams,
Between the side beam and the door inner panel, a mid panel is provided along the longitudinal direction of the side beam inside the window glass, and a door check and a door hinge are provided at one end of the mid panel, A door lock is provided at the other end of the mid panel, and a door sash is attached to the mid panel along the outer periphery of the upper part of the door.
Attach support plates on both sides of the
These support plates are fixed to the door inner panel, and the door sash is located between one side in the front-rear direction of the door sash and the mid panel.
Bridging the front sash of these a separate body, the front
Between the middle of the sash and the support plate and the door sash.
Between the other side of the shoe in the front-rear direction and the support plate.
Connected by single, front-rear direction other side and front of the door sash
Both side edges of the window glass to the cement sash slidably fitted, the mounting midplane one end and both sides of the door inner panel on the outside of the other end, respectively, the mid to the inside of both sides of the door outer panel One end and the other end of the panel are attached, respectively.

[0006]

[Function] When the door inner panel is attached to the mid panel, the door sash, front sash, door hinge, door check and door lock are attached to the door inner panel together with the mid panel, and only the mid panel is attached inside the door outer panel. In these doors
Wash, front sash, door hinge, door check
The door, door lock and door inner panel are attached to the door outer panel together with the mid panel.

When an impact is applied to the door outer panel from the outside of the vehicle body, a side beam disposed inside the door outer panel along the front-rear direction of the vehicle body causes a side beam of the door outer panel caused by an impact from the outside of the vehicle body. We suppress invasion of vehicle body inward. Since the front sash is formed separately from the door sash, the distance between the front sash that guides both sides of the window glass and the other side of the door sash can be adjusted by moving the mounting position of the front sash. It can be easily adjusted according to the width of.
