Abstract:
To provide a method which is favorable in a yield for attaching a frame structure to an attached member.SOLUTION: In a method for attaching a frame structure to an attached member by using a bolt, the bolt has a male screw part and a hollow flange, and a bottom part of the frame structure has a hole having a diameter larger than an outside diameter of the male screw part of the bolt, and smaller than an outside diameter of the flange of the bolt. The method has the steps for making a side face of the flange tightly adhere to an inner wall of the frame structure by elastically deforming the side face of the flange to the outside by a press to a head part of the flange in a state in which the male screw part is made to penetrate the hole of the frame structure, and attaching the male screw part to the attached member.SELECTED DRAWING: Figure 6
