Title:
CAST VEHICLE TIRE WHEEL AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH07101201
Kind Code:
A
Abstract:

PURPOSE: To reduce a weight of a cast wheel by forming an annular recessed corner part below a tire bead support face formed integrally with each of tire hold walls toward an inner side in the radial direction on one side of the tire bead support face.

CONSTITUTION: A rim member 4 is integrally formed in the radial direction on the outside of an annular disc part formed integrally around a hub member, and tire hold walls 5a, 5b and tire bead support faces 6a, 6b integral with the tire hold walls 5a, 5b are formed at both outer peripheral ends. A substantially annular recessed corner part 7 having a support 8 below the tire bead support face 6a is formed toward an inner side in the radial direction of the tire bead support face 6a, and a spoke part 9 separated in an opening part 10 is formed in a wheel part between the disc part and the rim member 4. Consequently, a tire wheel which does not impair familiarity with a tire is obtained with reduced weight of the cast tire wheel 1 and ensured in its strength by providing a light pocket.
