1. A filament winding apparatus comprising a rail extending in a first direction, a core material support device that supports a core material, and a winding device that winds a fiber bundle onto an outer peripheral surface of the core material, the winding device comprising:
a guide unit having an opening through which the core material passes, and guiding the fiber bundle; and
a main frame on which the guide unit is mounted; wherein
the main frame is movable relative to the core material in the first direction,
the main frame is movable in a second direction orthogonal to the first direction, and
the main frame is rotatable around a first rotational axis extending in a third direction orthogonal to each of the first direction and the second direction.
