Abstract
Disclosed is a filament winding device wherein an FRP layer is prevented from becoming thick by avoiding piled fibers in the case of the feeding of multiple filaments when a plurality of fibers are fed simultaneously. For realizing this theme, a filament winding device moves a fiber guide member equipped with a plurality of fiber feeding ports relatively in an axial direction of a wound member rotating relatively about the axis, and feeds fibers through the fiber feeding ports to wind the fibers around the wound member, wherein the fiber feeding ports are provided only in part of the fiber guide member. When the fiber guide member is moved relatively in the axial direction of the wound member, a plurality of fibers are fed only from one side when viewed from the wound member and the fibers are wound around the wound member while being gathered on the periphery of the wound member.
