Abstract
Stackable drawn sheet-metal pieces have spacer knobs which are drawn in a bead-type manner and are integrated in the drawn piece to rise from a wall of the drawn piece. The walls of the drawn piece situated transversely to a stacking direction have a mutual distance such that the walls, which are situated at an acute angle with respect to the stacking direction of the drawn piece, are at most in a loose contact with one another and reliably engage with one another in a no-lock manner. The spacer knobs are arranged in the stack above one another in the same position have a common axis which extends approximately in the center and is situated parallel to the stacking direction. The spacer knobs have the same construction with respect to their dimensions and alignment and that the diameter of the respective knob opening on at least one partial circumferential area is smaller than the diameter of the knob base. The diameter and the construction of the knob base and of the knob opening in this partial circumferential area are coordinated such that the drawn piece come to rest on one another in the stack in a manner which is stable in terms of tilting.
