Abstract
A spinning forming method includes a first forming step and a second forming step, in each of which a plate fixed to a main shaft is formed while being rotated. In the first forming step, a processing tool is brought into contact with a first main surface of the plate to form a first level-changing portion extending from the first main surface toward a second main surface. In the second forming step, the processing tool is brought into contact with the second main surface at an outer peripheral side of the first level-changing portion to form a second level-changing portion extending in an opposite direction to the first level-changing portion.
