Abstract
A filament winding apparatus prevents a fiber bundle supplied to a liner from interfering with other fiber bundles and fiber supplying guides. First and second guide units include a plurality of fiber supplying guides arranged radially and extending and contracting in a direction approximately perpendicular to a liner central axis. When a fiber bundle supplied from a first supplying guide of the first guide unit crosses between a second supplying guide of the second guide unit and the liner, the distance from the second supplying guide to the liner central axis is made larger than the distance from the first supplying guide to the liner central axis, and in the reverse case, the distance from the first supplying guide to the liner central axis is made larger than the distance from the second supplying guide to the liner central axis.
