Abstract
A nut is caulked and fixed to a plate material and a protrusion at an end of a collar is press-fitted into a recessed groove generated on the opposite surface of the plate material at the time of the caulking fixation, thereby fixing the nut and the collar to both surfaces of the plate material, respectively. The plate material is, for example, a metal panel, and the nut is, for example, a pierce nut. Since the collar is caulked and fixed, thermal strain is not generated.
