Beschreibung
Zusammenfassung:	The method includes providing a planar sheet part; forming the planar sheet part by drawing or conical spinning to the shape of a partially formed part made up of a plate and a provisional hollow portion extending from the plate with a revolution shape with respect to an axis perpendicular to the plate, and an end wall closing an end of the provisional hollow portion opposite to the plate; and elongating a section of the provisional hollow portion by cylindrical or conical spinning. The shock absorber is integral with a plate and an elongated hollow portion extending from the plate with a revolution shape. A section of the elongated hollow portion has a thickness that is thinner than the thickness of the plate.
