A manufacturing method for a hollow annular dry preform arranged on an outer periphery of an annular mandrel, the dry preform comprising a plurality of reinforcing fiber layers (13, 11, 12) each formed of reinforcing fibers aligned in a predetermined direction intersecting with that of an adjacent layer, the manufacturing method comprising: arranging a third reinforcing fiber layer formed of reinforcing fibers, which continue in an annular direction by the amount of at least one rotation and are aligned in the annular direction, on the outer peripheral surface of an annular mandrel, the fibres of the third reinforcing fiber layer being fed from an annular fiber-feeding portion and begin arranged through intermediation of a guide provided with a plurality of guide holes onto the outer peripheral surface of the mandrel; arranging a first reinforcing fiber layer by winding reinforcing fibers formed as a sheet-like reinforcing fiber-bundle spirally around an outer periphery of the annular mandrel, the reinforcing fibers of the first reinforcing fiber layer seamlessly continuing in the annular direction by an amount of at least one rotation, and being aligned in a direction in which the reinforcing fibers intersect at a predetermined angle (+θ) with respect to the annular direction; and arranging a second reinforcing fiber layer by winding reinforcing fibers formed as the sheet-like reinforcing fiber-bundle spirally around the outer periphery of the annular mandrel, the reinforcing fibers of the second reinforcing fiber layer seamlessly continuing in the annular direction by an amount of at least one rotation, and being aligned in a direction in which the reinforcing fibers intersect at a predetermined angle (-θ) with respect to the annular direction, the fibres of the first reinforcing fiber layer and the second reinforcing fiber layer being fed from a fiber winding portion and being wound around the outer peripheral surface of the mandrel through intermediation of a guide provided with a plurality of guide holes, wherein each of the orientation angles (θ) of the first reinforcing fiber layer and the second reinforcing fiber layer is set within a range of 20° to 70°, wherein the guide holes of the guide are arrayed in the annular direction, and hence the plurality of reinforcing fibers guided by the guide holes are arrayed in the annular direction so that the sheet-like fiber bundle is formed, and wherein the fiber winding portion and the guide are revolved around the mandrel so that the sheet-like fiber bundle is wound around the outer periphery of the mandrel. arranging a third reinforcing fiber layer formed of reinforcing fibers, which continue in an annular direction by the amount of at least one rotation and are aligned in the annular direction, on the outer peripheral surface of an annular mandrel, the fibres of the third reinforcing fiber layer being fed from an annular fiber-feeding portion and begin arranged through intermediation of a guide provided with a plurality of guide holes onto the outer peripheral surface of the mandrel; arranging a first reinforcing fiber layer by winding reinforcing fibers formed as a sheet-like reinforcing fiber-bundle spirally around an outer periphery of the annular mandrel, the reinforcing fibers of the first reinforcing fiber layer seamlessly continuing in the annular direction by an amount of at least one rotation, and being aligned in a direction in which the reinforcing fibers intersect at a predetermined angle (+θ) with respect to the annular direction; and arranging a second reinforcing fiber layer by winding reinforcing fibers formed as the sheet-like reinforcing fiber-bundle spirally around the outer periphery of the annular mandrel, the reinforcing fibers of the second reinforcing fiber layer seamlessly continuing in the annular direction by an amount of at least one rotation, and being aligned in a direction in which the reinforcing fibers intersect at a predetermined angle (-θ) with respect to the annular direction, the fibres of the first reinforcing fiber layer and the second reinforcing fiber layer being fed from a fiber winding portion and being wound around the outer peripheral surface of the mandrel through intermediation of a guide provided with a plurality of guide holes, wherein each of the orientation angles (θ) of the first reinforcing fiber layer and the second reinforcing fiber layer is set within a range of 20° to 70°, wherein the guide holes of the guide are arrayed in the annular direction, and hence the plurality of reinforcing fibers guided by the guide holes are arrayed in the annular direction so that the sheet-like fiber bundle is formed, and wherein the fiber winding portion and the guide are revolved around the mandrel so that the sheet-like fiber bundle is wound around the outer periphery of the mandrel.
