PURPOSE: A method for manufacturing a ball guide of a thrust ball bearing is provided to reduce stress and deformation of the thrust ball bearing by minimizing a processing degree of a guide section of the ball guide. CONSTITUTION: A drawing dice including a hole having a size identical to a diameter of a ball guide is prepared. The drawing dice has an arc-shaped protrusion, which is integrally formed with the drawing dice, in such a manner that a guide section is formed in a steel wire discharged from the drawing dice. The steel wire formed with the guide section is drawn from the drawing dice by means of a drawing device. Then, the steel wire formed with the guide section is bent by using a bending machine such that the steel wire has a diameter corresponding to a diameter of a thrust bearing. Then, the steel wire is cut by using a cutter.
