For a shopping cart, an undercarriage comprises a tubular frame and a tray, a back portion of which includes an integral basket having a front wall, a back wall, and two side walls. The frame has two lateral portions extending longitudinally between the front and back ends of the undercarriage, at a lower level and a transverse portion extending transversely near the back end of the undercarriage, at a higher level. The tray and the basket are made of welded wires. The back portion is disposed to rest against the transverse portion of the frame in a generally level position of the tray and is elevated in an upwardly tilted position of the tray. At the back portion, one of the wires defines a bail, which extends backwardly so as to overlie the transverse portion of the frame in the generally level position of the tray.
