A manufacturing device of a resin fuel tank can efficiently cool molded bodies when a cooling mold is inserted on the inside of the sheet-like molded bodies and shaping molds are closed. Here, semispherical convex portions are tightly formed on a surface of the cooling mold, and a contact area of the convex portions with the molded body gradually decreases in a boundary region of the molded body in which transition from an contact portion, with which the cooling mold contacts, to a non-contact portion, with which the cooling mold does not contact, is made. Thus, a temperature gradient of the molded body is suppressed in the boundary region, and formation of a groove in the boundary region can be suppressed. |
