2. Description of the Related Art Conventionally, a structure of a hemming portion of a vehicle outer panel such as a trunk, a bonnet, a door is shown in FIG.
By the steps shown in (b) and (c), the edge portion 1a of the outer plate 1 is folded back so as to wrap the edge portion 2a of the frame 2 to form the hemming portion 3, and the hemming portion 3 and the frame 2 are separated from each other. The plate 1 and the plate 1 are joined with an adhesive. A thermosetting resin is used as the adhesive, and is heated and cured in an oven or the like after the hemming process. When these members are conveyed to an oven or the like after hemming, the outer plate 1 of the hemming portion 3 and the frame 2 may relatively move. For example, as shown in FIG. 4, the hemming portion 3 of the outer plate 1 causes a spring back 5, and the frame 2 easily moves in the direction of the arrow 6. FIG. 5 shows the pressing state of the hemming press. When the pressing force 16 is increased to prevent the occurrence of the springback 5 (FIG. 4), the maximum load at the bending edge 18 on the surface of the outer plate 1 is shown. Since it becomes a change point of no load, a frame-shaped fold is generated at the outer plate surface position 17 corresponding to this change point, and this frame-shaped pattern is generated after painting, which serves as a part that attaches importance to the appearance. Absent. Therefore, it is necessary to take care of it, and this finishing labor is considerably increased, which is disadvantageous. Further, since the surface is pressed, even if the pressing force is increased to some extent, a sufficient coupling effect for stopping the movement of the frame and the outer plate of the hemming portion cannot be obtained.

Therefore, conventionally, in order to fix and hold the hemming portion 3 until the adhesive is completely cured, the hemming portion 3 is fixed by spot welding 19, MIG welding 20, etc., as shown in FIG. 6, for example. .. When the hemming portion 3 is fixedly held by the spot welding 19 or the MIG welding 20, there is a problem that the outer plate 1 is thermally distorted, and the surface finishing work of the outer plate 1 is required to correct this.

As a technique for solving such a problem, as shown in FIGS. 7 (a), 7 (b) and 7 (c), a frame side convex embossing 21 is formed in the vicinity of the end of the frame 2 forming the hemming portion. Incidentally, when the hemming portion is formed by the hemming press, the outer plate side convex embossing 22 matching the frame side convex embossing 21 is formed in the vicinity of the end portion of the outer plate 1 to form the convex embossing 21 on the frame 2 side. There is disclosed a technique of fitting the back surface of the convex embossing 22 on the outer plate 1 side to the front surface of the. (JP-A-2-75420). In this technique, the local embossing 21 is formed on the frame 2 in advance, the local relief 23 is provided on the upper mold 11 of the hemming press, and the rigidity of the frame 2 is used to form the local embossing 22 on the outer plate 1. It is a thing. Actually, since the frame 2 moves slightly inside the hemming portion of the outer plate 1, it is very difficult to completely match the hemming portion escape 23 of the upper die 11 of the hemming press with the position of the embossing 21 of the frame 2.
Moreover, since the plate thickness of the outer plate 1 is usually thicker than the plate thickness of the frame 2, the local embossing 21 provided on the frame 1 is
Since it is deformed by the outer plate 1, it is difficult to mold the embossing 22.

According to the method of the present invention, the pressing recess of the hemming portion can be easily formed, and a step such as welding is not required. In addition, there is no need for subsequent maintenance due to heat distortion or the like. If the pressing force of the hemming press is applied to the lid of the trunk, 90
When the pressure is about tons (surface pressure of 300 to 400 kg / cm 2 ), relative movement between the outer plate and the frame may occur, and when 120 tons (surface pressure of 500 kg / cm 2 or more) is applied, the relative movement disappears. Causes a frame pattern on the outer plate surface side. In the method of the present invention, about 90 tons achieves the purpose sufficiently and does not require excessive pressing force. Further, it is possible to suppress springback of the bent portion of the outer plate without applying an excessive pressing force.
