The invention relates to a metal element, a joint structure, a joint, and a method for manufacturing the joint. Provided is an element that can be firmly bonded to a metal plate even if a shape that is difficult to process (a shape required for bonding) is not imparted in advance. The element (1) has a flange-like portion (2) and a cylindrical portion (3) having a smaller diameter than the flange-like portion (2). Furthermore, in a state in which a cylindrical portion (3) is inserted into a through-hole (12) formed in a metal plate (11), pressure is applied in the axial direction, thereby causing the metal plate (11) to deform and flow in the compression direction by means of the flange-shaped portion (2), and causing the tip edge portion of the cylindrical portion (3) to deform so as to expand the diameter so as to block the deformed and flowing metal. Thus, the element (1) can be bonded to the metal plate (11) made of metal.
本发明涉及金属元件、接合结构、接合件和接合件的制造方法。提供即使未预先赋予加工困难的形状(接合所需的形状),也能与金属板牢固地接合的元件。元件(1)具有凸缘状部分(2)以及与所述凸缘状部分(2)相比为小径的圆柱状部分(3)。而且,在将圆柱状部分(3)插入到金属板(11)上穿设的穿通孔(12)中的状态下,通过在轴向上施加压力,由所述凸缘形状部分(2)使所述金属板(11)在压缩方向上变形流动,且使圆柱状部分(3)的顶端缘的部分以扩径的方式变形以便挡住变形流动的金属,从而可以使所述元件(1)接合于由金属构成的金属板(11)。
