A first step of setting a steel material heated to a temperature not lower than an A1 transformation point on a forming table and a second step of punching a ring-form member from the steel material and thereafter forming and quenching the ring-form member on the forming table are included. A press die is constructed to be dividable into an inner cylinder and an outer cylinder. In the second step, the ring-form member is punched from a coil material by pressing a tip end portion of the inner cylinder and a tip end portion of the outer cylinder against the coil material. The punched ring-form member is formed and quenched by further pressing a tip end of the inner cylinder against the ring-form member while the ring-form member is held between the outer cylinder and a forming die.
