Abstract
PURPOSE: To prevent a wheel disc from reducing in strength with time by forming grooves on a hub face of a wheel disc for avoiding mutual contact of the hub face and an opening edge of a groove in the hub, thereby achieving good plane precision of a hub face in contact with a disc.
CONSTITUTION: A hub face 4 of a disc 3 welded with a rim 1 having side rings 2 is drilled to form a plurality of bolt holes 7. Nut seats 7a are respectively shaped around the bolt holes 7. Grooves 8a, 8b arranged concentrically with the circumference of a hub hole 5 continuously into the inside of each nut seat 7a. Positions of the grooves 8a, 8b are on opening edges 10a, 10b of a channel 10 which depresses into the hub 9 and prevents each square flange 12 on a stud bolt 11 from coincident movement with it. Thereby the edges 10a, 10b are prevented from direct contact with the hub face 4 and good plane precision can be attained on the hub face 4.
