NUT FOR PRESS-FIT JOINING, PRESS-FIT JOINING STRUCTURE AND PRESS-FIT JOINING METHOD USING THE SAME

摘要

An object of the present invention, a vehicle, and used for bonding of the element plates, structural members, brackets, etc. to configure the machinery, joining is made easily and satisfactorily excellent bond strength, cost effectiveness, even a fastening member for the excellent press-bonded, and that to provide a press-fit junction. ; With the threaded portion (4) from the base part (3) In addition, the threaded portion (4) has a protrusion formed in the projection 6 with larger diameter than. Projections 6, sheet material 8 to form a hole portion 10 to be solid-phase bonded by a press-fit that involves electric resistance heat, and also to form an end face of the hole portion 10 and the other similar shape predetermined putting the value of (d) is formed to push.
