Abstract
A method for manufacturing a yoke includes forming a through-hole that is open in a yoke bottom surface and a cylindrical bearing support portion by burring an edge of the through-hole using a burring punch, wherein the burring punch is located on a base end side at a distance from a cylinder front-end portion of the bearing support portion so as to form a ring-shaped flange portion inclined toward an inner radial side on the cylinder front-end portion of the bearing support portion.
