Abstract
A filament winding device includes: a supporting unit that supports a mandrel on which a plurality of fiber bundles impregnated with a resin are wound, the supporting unit movable in the axial direction of the mandrel; and a helical unit having a plurality of fiber bundle guide units arranged radially in the circumferential direction of the mandrel and guide the corresponding plurality of fiber bundles to the mandrel, the helical unit supplying the plurality of fiber bundles to the mandrel through the fiber bundle guide units. Each of the fiber bundle guide units has a pressing roller for pressing a fiber bundle supplied to the mandrel, against the circumferential surface moving in the axial direction. The pressing roller can come into the contact with the circumferential surface of the mandrel and be rotationally driven about a roller axis extending in a roller axis direction perpendicular to the axial direction.
