Patent Searching and Data


Title:
VEHICLE WHEEL
Document Type and Number:
WIPO Patent Application WO/2012/108339
Kind Code:
A1
Abstract:
A groove (30) is formed in a wheel radial inner surface (24b) of an exterior bead seating section (24) of a rim (20). The groove (30) is provided with a groove side inclined surface (31) that is inclined at an angle less than the angle of inclination of the wheel radial inner surface (24b) of the exterior bead seating section (24) in the area (24c) where no groove (30) is formed, and that is inclined axially outward with respect to the wheel and radially outward with respect to the wheel. Because the groove side inclined surface (31) is inclined axially outward with respect to the wheel and radially outward with respect to the wheel, compared to a case where the groove side inclined surface (31) is cylindrical, the groove (30) is less deep, and the minimum thickness of the exterior bead seating section (24) is greater at the wheel axial direction position at which the groove (30) is formed. Thus, the strength of the rim (20) can easily be maintained even if the groove (30) is formed in the exterior bead seating section (24).
