Document Type and Number:
Japanese Patent JP4963409
Kind Code:
B2
Abstract:
The invention provides a fastening method and a fastening tool which can stably fasten a nut to a bolt securely and with a small dispersion at a desired axial force. A fastened member (20) is fastened by inserting abolt (21) to the fastened member (20), thereafter temporarily fastening a nut (22) and the bolt (21), pulling a leading end (21b) of a shaft portion (21c) of the bolt (21) in an axial direction of the bolt (21), rotating the nut (22) so as to screw into the bolt (21) while elastically deforming the bolt (21) so as to generate an axial force, and thereafter canceling the pulling of the bolt (21).
