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.
【課題】リベットの締結力を向上する。【解決手段】リベット1は、頭部2と、頭部から頭部の中心軸方向に突出するシャンク部3とを有し、FRP5からFRPに積層された金属部材4に向かって、頭部へ荷重を加えることで、シャンク部の先端側を広げて、金属部材とFRPを締結するリベットであって、シャンク部は、頭部からの突出長さを異にする短尺部3bと長尺部3cとを含んでおり、それぞれの長さが異なることから、互いに干渉し難く、リベットの径方向に広がり易いため、広範囲に亘って金属部材を固定できる。【選択図】図2
