Abstract
A toroidal pressure vessel having extremely high pressure resistance has laminated latitudinal reinforcing fiber layers to improve a strength in a latitudinal direction of the pressure vessel. Moreover, putting reinforcing fibers constituting those laminated latitudinal reinforcing fiber layers in continuity enables further improvement of strength in the latitudinal direction of the pressure vessel, for example compared with a case where the reinforcing fibers are divided for each layer.
