Abstract
The invention relates to an energy guiding chain, with chain links (1, 2) each comprising two side straps (3, 4). The side straps (3, 4) form opposite strap strands transversely to their longitudinal direction, where at least some of the opposite side straps (3, 4) are connected to each other by cross-members (5, 6), the ends of at least some of which display a bearing area (7) with an essentially cylindrical journal (10), extending in the longitudinal direction, for pivotable mounting in a bearing seat (8) on an associated side strap (3, 4). To improve the angular stability of the side straps when the cross-member is opened, it is proposed that the journal (10) display a first flattened section (12) on its lateral surface. To receive the journal (10), the bearing seat (8) comprises an essentially cylindrical space (13) with a flattened section (15), where the flattened section (15) of the cylindrical space (13) and the first flattened section (12) of the journal (10) lie opposite each other in a closed position of the cross-member (5, 6).
