As shown in FIG. 7B and the enlarged view of FIG. 7C, the caulking piece 83 and the plate 90 are formed with thin caulking convex portions 89 and caulking bent portions 92 by the caulking. At that time, plate 9
0 deforms 94 the opening side of the concave groove 87 to the side opposite to the caulking direction around the corner of the step portion 88a on the tip side of the caulking receiving groove 88, and the caulking piece 86 of the shape member 82 is also wound to the hollow portion side. It will be deformed as shown. In this way, when the deformation 94 or the like occurs only in the caulking portion, the plate 90 becomes distorted in the longitudinal direction in a swelling manner, the buckling strength of the plate 90 decreases, and the entire structural member 80 assembled by the caulking. The strength will be impaired. Further, such deformation 94 narrows the fixing by caulking only to the point-like fitting portion between the caulking bent portion 92 and the caulking receiving groove 88. Therefore, there has been a problem that the connection strength between the shape member 82 and the plate 90 is significantly reduced from the intended design. Moreover, the plate 90 and the profile 82
When the so-called pressing plate is arranged around the punch P and the receiving plate is arranged on the opposite side, and the two are constrained so as to sandwich them at the time of driving, the amount of curling is reduced, but the caulking piece 86 is deformed by spring back. The deformation that remains is left.

メ装置を提供することを目的とする。Such deformation produces a gap S between the profile 82 and the plate 90. Therefore, while being used as the hollow structural member 80, if various external forces are applied, the gap S expands, and the caulked portion may start to rattle, or may seriously come off. In addition, there is a risk that rainwater or dust may enter the space S and the caulked portion may stain the inside of the hollow structural member 80 from the base or cause corrosion or the like. Furthermore, when the beam or the like is attached to a place where the beam can be seen indoors or outdoors, the deformation exposes a state in which the plate is distorted in the longitudinal direction, which is unsightly from an aesthetic point of view. The present invention solves the above problems in the conventional caulking, prevents the above-mentioned distortion and deformation in the caulking portion of the two members such as the shape member and the plate material, obtains the desired connecting strength, and the vicinity of the caulking portion. It is an object of the present invention to provide a caulking structure, a caulking method, and a caulking device used for the caulking method, which allow the original caulking to be performed without forming the above gap.

る面取り状の変形部である。When the punch 20 descends, the tip of the punch portion 22 first comes into contact with the outer surface of the caulking piece 3 of the first member 1 and, as shown in FIG. 1 (B), comes into contact with the caulking piece 3. The portion is deformed following the conical shape of the punch portion 22 to form the downward crimping convex portion 6 on the crimping piece 3 (see FIG. 2C). At the same time, a portion of the end portion of the second member 10 in the concave groove 2 located on the caulking receiving groove 5 is thin and hemispherical around the caulking convex portion 6 according to the pressing of the punch portion 22. The crimped bent portion 12 is formed. As a result, the crimped portion 9 is formed. When the punch 20 is lowered, the punch unit 2
As shown in FIG. 1 (B), the tip of 2 reaches the position in the caulking receiving groove 5, and the pressing surface 32 of the pressing body 30 presses the outer surface of the caulking piece 3 of the first member 1. . At the same time, the pressing ridge 34 of the pressing body 30 abuts on the tip edge of the crimping piece 3, and the taper surface 36 thereof moves the tip edge of the crimping piece 3 and the second member 10 adjacent thereto along the longitudinal direction. Apply a bending force to bend by pressing downward. Since the tip of the lower caulking piece 4 is shorter by a few millimeters, the edge of the caulking piece 3 can be bent. The amount of deformation due to this bending force is set to be larger than that in which the deformation is flat as shown by the broken line in the figure, in consideration of the amount of return due to springback. In addition, it is necessary to prevent the leading edge of the crimping piece 3 from rolling up and to prevent a gap from being formed between the crimping piece 3 and the second member 10. Therefore, the height of the pressing ridge 34,
The adjustment is performed in consideration of the angle of the tapered surface 36, the deformation amount of the tip edge of the crimping piece 3, the material and the thickness of the second member 10, and the like. As described above, the crimping of the crimping piece and the deformation of the second member (plate), which have conventionally occurred during crimping, are shaped during crimping. Reference numeral 8 in the drawing denotes a chamfered deformation portion formed on the tip edge of the caulking piece 4 when the pressing ridge 34 receives a bending force.
