Japanese Patent JP3686350
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a disk wheel for an automobile having a nut fastening bearing surface allowing the use of both a tapered nut and a spherical nut.
SOLUTION: The nut fastening bearing surface 13 is formed of a tapered face 11 and a spherical recessed face 12 continuous in the direction of inside and outside. With this constitution, in case of using the tapered nut 21, the tapered nut 21 is force-fitted to the tapered face 11, and in case of using the spherical nut 22, the spherical nut 22 is force-fitted to the spherical recessed face. The disk wheel 1 and an axle can thereby be fixed and held with sufficient force in either case of using the tapered nut 21 or spherical nut 22.
