A bead forming method includes the steps of preparing a bumper stay 10 having a partition wall 12 that partitions an internal space and extends in a longitudinal direction, an elastic body 40 that can be inserted into the bumper stay 10, and a pusher 61 that presses the elastic body 40; inserting the elastic body 40 into the bumper stay 10 and arranging the elastic body 40 in the bumper stay 10 so as not to come into contact with the partition wall 12; and forming a buckling bead 11a by compressing the elastic body 40 in the longitudinal direction of the bumper stay 10 by the pusher 61 to expand the elastic body 40 outward in a radial direction without coming into contact with the partition wall 12, thereby bulging a part of an outer wall 11 of the bumper stay 10 outward in the radial direction without deforming the partition wall 12.
