PURPOSE:To improve the durability by fixing a wheel onto a car through an annular pressing jig, thus making uniform the stress distribution which becomes high on the periphery of a nut seat and reducing the max. stress itself. CONSTITUTION:A wheel 1 is tightened by wheel nuts 3 through an annular pressing jig 4. Therefore, the stress distribution which becomes high on the periphery of a nut seat is made uniform, and the max. stress itself can be reduced, and duration strength can be improved. A thickness of 2-6mm. is suitable, and a width of 30-40mm. is desirable. |
