<p>PROBLEM TO BE SOLVED: To improve fastening force of a rivet.SOLUTION: A rivet 1 includes a head part 2, and a shank part 3 projecting from the head part toward the central axis direction of the head part; and widens the tip side of the shank part to fasten a metal member 4 and an FRP(Fiber Reinforced Plastic) 5 by applying a load to the head part from the FRP toward the metal member 4 laminated on the FRP. The shank part has a short-length part 3b and a long-length part 3c that are difference in a projection length from the head part, and since the lengths of the short-length and long-length parts are difference, they are hard to interfere with each other, and since they are easy to widen in the radial direction of the rivet, the metal member can be fixed over a long range.</p> |
