Abstract

PURPOSE: To provide a fastening member not necessary to fasten time and again without increasing its weight and thickness by forming a protrusion on the surface around the bolt hole of the fastening member and a notch on the back surface. CONSTITUTION: A fastening member 1 is fastened to a fastened member 2 by a bolt 3 penetrating through bolt holes 11, 21 and a nut N via a washer W. The portion of the surface of the fastening member 1 around the bolt hole 11, which contacts a seat face 32 of the bolt 3 protrudes slightly from the outer flat portion, forming a buffer portion having a space in the back. In other words, an annular protrusion 61 having a diameter approximately as same as that of the seat face 32 of bolt 3 is arranged on the surface around the bolt hole 11 of the fastening member 1. Moreover, an annular recessed notch 62 having a diameter larger than that of the bolt hole 11 is formed on the back surface of the fastening member 1 around the bolt hole 11. The buffer portion is formed as one piece with the fastening member 1 by pressing the portion of the fastening member 1 around the bolt hole 11.
