The present invention discloses a riveting method and a riveting structure. The riveting method comprises providing a plate having a first side and a second side opposite to the first side; forming a wall portion on the first side of the plate, the wall portion having a first recessed area at its first side and a second recessed area at its second side opposite to the first side; placing the fastener in the first recessed area so that the fastener is adjacent to the first side of the wall portion; and applying a force to the wall portion from the second side of the wall portion so that the wall portion is deformed so as to at least partially enclosed the fastener. This technical solution can avoid unwanted indentation on the back of the plate.

The invention relates to a method for producing a connecting element comprising at least two ball-like sections, wherein two ball-like sections are directly adjacent to each other, or wherein two ball-like sections are connected to each other by means of a connecting section, wherein the rolling of a single-piece blank, which is cylindrical at least in sections, between at least two rolling tools and the shaping of the at least two ball-like sections and optionally of the connecting section during the rolling are provided.
