A side frame 1 of a grooved or channel-shaped sectional configuration has a bottom wall 2 and sidewalls 3 and 4. A first stiffener 9 closing a portion of an open upper surface of the side frame 1 and a second stiffener 10 superposed on the bottom wall 2 are welded to the side frame 1 to reinforce the side frame 1. A cup-shaped spring base 11 is fitted from below into and welded to openings 2 1 and 10 3 defined in the bottom wall 2 and the second stiffener 10, and an upper end of a coil spring 19 is accommodated within the spring base 11. The side frame 1, which is reduced in rigidity due to the opening 2 1 can be reinforced with the first and second stiffeners 9 and 10, whereby a sufficient rigidity of the side frame can be ensured.

Un cadre latéral 1 comportant une section en forme de rainure ou de profilé en U comprend une paroi inférieure 2 et des parois latérales 3 et 4. Un premier raidisseur 9 fermant une partie de la surface supérieure ouverte du cadre latéral 1 et un deuxième raidisseur 10 superposé à la paroi inférieure 2 sont soudés au cadre latéral 1 pour renforcer ce dernier. Une base de ressort en forme de cuvette 11 est montée à partir du dessous dans les ouvertures 2 1 et 10 3, et soudée à ces dernières, lesquelles sont délimitées dans la paroi inférieure 2 et le deuxième raidisseur 10, et l'extrémité supérieure d'un ressort à boudin 19 est ajustée dans la base de ressort 11. Le cadre latéral 1, dont la rigidité est réduite à cause de l'ouverture 2 1, peut être renforcé par les premier et deuxième raidisseurs 9 et 10 pour lui assurer une rigidité suffisante.
