    摘要: A vehicle seat belt webbing retractor (10) includes a frame (40) and a spool (32) on which belt webbing (16) is wound. The spool (32) has a longitudinal axis (64) about which the spool rotates in a belt withdrawal direction (86) and in an opposite belt retraction direction (88). A shaft (34) supports the spool (32) on the frame (40) for rotation about the axis (64). The shaft (34) has at least a pair of tubular portions (154, 156) which extend parallel to the axis (64) and which are longitudinally coextensive along the axis. The tubular portions (154, 156) extend between spaced side walls (48, 50) of the frame (40). The tubular portions (154, 156) provide increased bending strength for the shaft (34).
