Jigs (52 to 57) are respectively set on upper and lower holders (21, 31) of a button attaching apparatus instead of upper and lower dies; relative position of the upper and the lower holders (21, 31) is adjusted while upper and lower springs (211, 317) are disabled; while the upper spring (211) is kept disabled, the lower spring (317) having stronger biasing force is enabled to adjust the lower spring; and the upper spring (211) is enabled to adjust the upper spring. |
