SPARE-TIRE INSTALLATION STRUCTURE

WIPO Patent Application WO/2011/004240

A4

A rim width (1) between inner and outer rim rings (17a, 18a) of a spare tire wheel (11) is substantially equal to substantially the entire height (hi) of a tire body (12) in a substantially horizontal position. The inner and outer rim rings (17a, 18a) are disposed on inner and outer drum portions (17, 18), respectively, joining at a junction (19). The junction is located adjacent to the position of a top surface of a rear cross member (6) in the vertical direction of the vehicle. A wheel-fracture facilitating member (20) protrudes from a rear surface (6a) of the rear cross member toward a spare-tire installation area (9) with an acute end (20a) thereof facing the inner drum portion (17). When the spare tire wheel (11) is fractured at the junction (19) by the rear cross member (6), the inner drum portion (17) is easily crushed by the wheel-fracture facilitating member (20).
