Abstract

PURPOSE: To improve the mounting accuracy to a wheel hub by piercing annular grooves on the circumference of the part to become the hub flat face part of an equal thickness plate body and tapering the outer side part of the annular grooves.
CONSTITUTION: In an equal thickness plate body A of a circular shape having a guide hole 4 at the center, concentrical annular grooves 3 are formed respectively on both sides of the circumference of the part to become hub flat face parts 2. Thence, tapered faces 1 are formed from the part of the annular grooves 3 toward the outside circumferential side by rolling rolls in such a manner that the circumferential edge 5 becomes thin. The tapered faces 1 are then drawn to form a disc. In this case, the plastic flow of the material on the front side of the hub flat face parts 2 is prevented by the annular groove 3; therefore, the hub flat face parts 2 assume approximately uniform plate thickness. Thereby, the disc member may be mounted surely and well with good accuracy to a wheel hub.
