Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automobile door.

[0002]

[Prior art]

 As shown in FIG. 6, an automobile door is formed with a door body 04 having an outer panel 01 and an inner panel 02 joined to each other and a space portion 03 therebetween, and a window glass is moved up and down in the space portion 03. A glass elevating mechanism (not shown) is provided, and the vehicle interior side of the inner panel 02 is covered with a door trim 05. Further, the lower end portion of the inner panel 02 is brought into contact with a side sill on the vehicle body side to externally expose the vehicle interior. A structure in which a weather strip 06 for sealing is attached is common (see, for example, Japanese Patent Laid-Open No. 62-1625).

Further, in an automobile door having such a structure, an opening portion through which a window glass comes in and goes out is provided in an upper portion of the door body 04, and rainwater and dust that have entered through the opening portion are lifted and lowered. In order to prevent entry into the vehicle interior from the hole 02a opened in the inner panel 02 for mounting a mechanism or door lock, the hole 02a is usually closed in the space portion 03 of the door. For example, a sealing screen 07 made of a thin film of vinyl or the like is spread.

[0004]

[Problems to be solved by the device]

 By the way, in the case of an electric elevator (power window) specification for automobile doors, electrical components such as a drive motor for the glass lifting mechanism are installed in the space 03, and these electrical components are connected to switches on the door trim 05 side. I need to do it. In such a case, a slit 07a for wiring the harness 08 is formed on the ceiling screen 07. However, water and dust that have entered the space 03 from the upper opening (not shown) enter the slit 07a. There is a problem that there is a possibility that the door trim 05 may enter the vehicle compartment side from the sealing surface by the weather strip 06 as shown by the arrow in the figure.

In addition, in the conventional automobile door, since the weather strip 06 is provided on the inner panel 02 as described above, the operation of attaching the weather strip 06 is performed by the door attached to the vehicle body. This is a work in which the posture of mounting from the lower side of the main body 04 is unfavorable, which makes it difficult to visually check the location where the weather strip 06 is mounted, resulting in poor workability.

By the way, when the ceiling screen 07 is provided as described above, there are differences in specifications such as the presence or absence of the slit 07a in the ceiling screen 07 between the power window specification and the manual elevating specification, which increases manufacturing labor and costs. Up, a problem that the mounting surface of the ceiling screen 07 needs to be formed in the door body 04, and the degree of freedom in the shape of the door body 04 is reduced accordingly, and the assembly of the door body 04 In the latter case, for example, when the ascending / descending path of the window glass is adjusted by the elevating device, it is necessary to remove the ceiling screen 07, which causes a problem that the adjusting work is troublesome.

The present invention has been made in view of the above problems of the prior art, and its main purpose is to improve the sealing property and improve the workability of attaching the weather strip.

[0008]

[Means for Solving the Problems]

 That is, according to the present invention, in a vehicle door in which the vehicle body side of the door body is covered with a door trim, a weather strip for contacting the vehicle body and sealing the vehicle interior to the outside is attached to the door trim.

[0009]

[Action]

 When installing the weatherstrip, attach the weatherstrip to the door trim before it is attached to the door body, and then attach this door trim to the door body that is mounted on the vehicle body. Therefore, it is not necessary to perform work in a posture in which workability is poor, such as when the door body is attached from the bottom of the vehicle body.

Further, when rainwater or the like enters the inside of the door body through the opening or the like through which the windshield goes in or out, the water or dust that has entered the inside of the door trim leaks out between the edge of the door trim and the door body. Since the seal between the automobile door and the vehicle body of the present invention is formed by the weather strip attached to the door trim, the edge of the door trim is located on the outer side of the vehicle from the seal portion by the weather strip. Water and dust that have leaked out between the edge of the door trim and the door body are discharged to the outside of the vehicle rather than the sealed portion.
