| 摘要 |
The invention relates to a functional element ( 10 ) comprising a longitudinal axis ( 14 ), a body part ( 16 ), a hollow pressed part ( 18 ), an annular supporting surface ( 20 ) which is arranged on the body part, substantially extended in a perpendicular direction with respect to the longitudinal axis and is radially displaced away from the pressed part and an annular groove ( 21 ) which axially extends and is embodied in the body part radially inside the supporting surface. Locking ribs ( 26 ) are preferably provided and at least partly cross the annular groove and the free end ( 28 ) of the pressed part is provided with a annular cutting edge ( 30 ). The inventive functional element is characterised in that an annular bulge ( 32 ) is embodied on the pressed part between the annular supporting surface and the free end of the pressed part and an annular cavity ( 34 ) is embodied around said pressed part between the bulge and the front free end thereof. An assembling component consisting of the functional element combined with a metal sheet, a method for producing the assembling component and a method for producing the functional element are also disclosed.
