摘要

The base section (2) has a bottom wall (7) defining two lower longitudinal edge regions (6); and each of them is provided successively without interruption with: a first portion (8) as an extension of the raceway (1) bottom wall (7), which extends slopingly upwardly and outwardly; a second downwardly directed portion which, with the first portion (8), externally forms an inverted valley (9); and a third upwardly directed portion which, with the downwardly directed portion, forms externally an inverted hip (10) which is at a higher level than the level determined by the lower surface of the bottom wall (7). <IMAGE>
