Title:
NUT-HOLDING MEMBER AND BOLT-JOINING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/026407
Kind Code:
A1
Abstract:
A nut-holding member used when joining a plurality of substrates having bolt holes by means of a bolt, the nut-holding member comprising: a nut insertion part into which a nut is inserted so as not to rotate with the screwing in of the bolt; a step section that the upper surface of the nut abuts, the upper surface being on the opposite side of the nut from the bearing surface; and a fastening part for holding the nut in a disengagement-preventing state so as to prevent the nut inserted into the nut insertion part from disengaging. The fastening part has a shape that protrudes on the bearing surface side, which is the surface of the nut inserted into the nut insertion part that faces the substrate, or a shape provided with a projection that protrudes on the upper surface side of the nut and hooks on the screw grooves. The fastening part changes shape when the tip of the bolt is screwed into the nut, causing the disengagement-preventing state of the nut to be released.
