Abstract:
The present invention provides a technique for suppressing an occurrence of weld in a pressure vessel liner. A film gate for molding a pressure vessel liner is located on a radially outer side of an outer peripheral end portion of an meshing portion in the pressure vessel liner. By disposing the film gate on the radially outer side of the meshing portion with a sufficient space between, it is possible to control the flow rate of the molten resin during molding, thereby suppressing an occurrence of weld.
