    • PROBLEM TO BE SOLVED: To provide a blind rivet having superior water tightness.SOLUTION: The blind rivet 1 is composed of a mandrel 2 and a rivet 3. The mandrel is formed into a round rod shape as a whole, and has a head 12 larger in diameter than the other portion at one end. The river has a rivet body 15 which is cylindrical as a whole and closed at its one end, and a flange 16 which is continuous to the other end of the rivet body and expanded to the outside of the radial direction of the rivet body. Furthermore, the rivet accommodates the mandrel by making the head positioned at the closed one end and locking the head so as to be undrawable. The rivet body has a tapered part 21 which is gradually reduced in outside diameter as progressing toward one end side from a connecting portion with the flange.
    • 要解决的问题:提供具有优异的防水性的盲铆钉。 解决方案:盲铆钉1由心轴2和铆钉3组成。心轴整体形成为圆棒形状,并且在一端具有直径大于其他部分的头部12。 该河具有一个整体为圆柱形且在其一端封闭的铆钉体15,以及与铆钉体的另一端连续并且膨胀到铆钉体径向外侧的凸缘16。 此外,铆钉通过使头部位于封闭的一端并锁定头部以使其不能被牵引而容纳心轴。 铆钉体具有从与凸缘的连接部朝向一端侧前进的外径逐渐减小的锥形部21。 版权所有(C)2012,JPO&INPIT
