Abstract
A hollow extruded frame formed by extruding a light alloy. The frame is formed from a peripheral wall part which, in a cross-section perpendicular to a longitudinal direction of the frame, has a short axis and a long axis. A plurality of confluent parts positioned so as to be symmetrical with respect to the short axis is formed on an inner side of the peripheral wall part or on the peripheral wall part. Three wall parts extend radially at equal angles of 120° from the confluent parts.
