ある。 1 and 2 show a first embodiment of the present invention, and in particular, FIG. 1 is an enlarged sectional view corresponding to FIG. 7 described above regarding the conventional device. That is, a cushioning material 3 is interposed between the outer peripheral flange 2a of the inner panel 2A and the back surface of the outer peripheral part of the outer panel 1A, and the hemming part 1a formed on the outer peripheral part of the outer panel 1A is connected to the outer peripheral flange 2.
By folding back to the back side of a, the inner panel 2A
It is the same as the conventional method in that it is assembled to the outer panel 1A.

けでヘミング隙間H1の内部に充分な防錆被覆層
を形成できることになる。 The structure of the vehicle body panel assembly according to the first embodiment is as follows:
With the structure as described above, due to the presence of the embossed portion 4, a hemming gap H1 sufficiently open to the outside is formed between the back surface of the outer peripheral flange 2a in the assembled state and the hemming portion 1a. Therefore, during the car body painting process, the assembled car body is coated with degreasing liquid,
When immersed in a chemical conversion treatment liquid and an electrodeposition coating liquid in sequence, the electrodeposition coating liquid penetrates through the space between the embossed portions 4 from the opening a that is sufficiently open to the outside, and is applied to the inner surface of the hemming portion 1a. A rust-proof coating layer is formed. Therefore, according to the present invention, it is possible to perform sufficient rust prevention treatment on the vehicle body panel assembly portion without applying a special sealant S to the opening a, but it is possible to perform a more complete rust prevention treatment. For this purpose, a sealant S may be applied to the opening a as shown by the imaginary line in FIG.
To explain this in detail with respect to the relationship curve between the coating area ratio of the electrodeposition liquid and the hemming gap shown in Figure 3, as can be understood from Figure 3, when the hemming gap reaches about 200 microns, the electrodeposition Since the coating area ratio of the liquid is close to 100%, it is possible to form a sufficient anti-rust coating layer inside the hemming gap H1 by simply setting the height of the hemming gap H1 , that is, the height of the embossed part 4 to about 500 microns. become.

ヘミング隙間H2に連絡している。 FIGS. 4 and 5 show a second embodiment in which a plurality of rows of embossed portions 4A, 4B are formed on the outer peripheral flange 2a of the inner panel 2B. These embossed portions 4 are brought into contact with the back surface of the outer panel 1B.
The embossed portion 4B formed on the inner peripheral side of A is brought into contact with the inner surface of the hemmed portion 1a. Therefore, the outer peripheral flange 2a of the inner panel 2B is spaced apart from the general part and the hemming part 1a of the outer panel 1B, and both surfaces of the outer peripheral flange 2a are provided with the embossed part 4.
It communicates with the internal space between the inner panel 2B and the outer panel 1B and the hemming gap H2 through the space between A and the embossed portion 4B.

に保持されるので、防錆機能が向上する。 The structure of the vehicle body panel assembly according to the second embodiment is as follows:
With the structure described above, the electrodeposited liquid, etc. in the car body painting process is distributed to the back surface of the outer panel 1B, the inner surface of the hemming portion 1a, and the outer peripheral flange 2a, which is sufficiently separated from these by the embossed portions 4A and 4B. The rust-preventive coating layer is formed on these surfaces. Therefore, the same effects as in the first embodiment can be expected with this structure, but when the structure of this embodiment is applied to an automobile door, the rust-preventing wax applied to the inside of the door will be coated around the outer periphery flange 2a. Since it is held in space, the rust prevention function is improved.
