Abstract
In a tank manufacturing method using a helical winding device that winds fiber bundles around a mandrel, the device includes: a first guide ring having an opening to pass the mandrel therethrough and placed around the mandrel with an axial center of the mandrel being taken as a center; and a plurality of first guide portions placed in the first guide ring along a circumferential direction around the axial center and configured to supply first fiber bundles to the mandrel. The method includes: moving the mandrel relative to the first guide ring along an axial center direction along the axial center such that the mandrel passes through the opening; and winding the fiber bundles around the mandrel while relatively moving the mandrel in the moving, by the first guide portions supplying the first fiber bundles to the mandrel with the first guide portions swinging in the circumferential direction.
