HIGH-PRESSURE TANK, MANUFACTURING METHOD FOR HIGH-PRESSURE TANK, AND MANUFACTURING DEVICE FOR HIGH-PRESSURE TANK

Abstract:

A high-pressure tank, a manufacturing method for a high-pressure tank, and a manufacturing device for a high-pressure tank capable of simplifying a shape of a metal fitting and performing high-speed FW molding without causing an idle rotation of the metal fitting or a deformation of a liner, for example, when performing the high-speed FW molding are provided. A high-pressure tank includes a liner, a reinforcing fiber layer, and a metal fitting. The reinforcing fiber layer is formed on an outer peripheral surface of the liner. The metal fitting is attached to the liner. The liner includes a liner main body and a protrusion part is provided in a part (cylindrical part) of the liner main body. The protrusion part is formed to protrude in a direction moving radially inward from the cylindrical part and to be fittable to a rotating shaft.
