1. A production device for production of fuel tanks having two or more built-in components, the production device comprising:
a first jig having two or more first built-in components placed thereon, when a first fuel tank is molded, so that the two or more first built-in components are built in the first fuel tank;
a second jig having two or more second built-in components placed thereon when a second fuel tank is molded, to provide for the two or more second built-in components to be built in the second fuel tank;
a pair of molding dies;
a lifting device including a support rod, a pedestal, and a slide mechanism, and the lifting device is configured to support:
the first jig when the first fuel tank is molded, and
at a subsequent time, the second jig when the second fuel tank is molded; and
at least one feed device configured to feed the first jig, having the two or more first built-in components placed thereon, to a position below the molding dies, so that the first jig is supported by the lifting device when the first fuel tank is molded;
the at least one feed device is configured such that following completion of molding of the first fuel tank, the at least one feed device performs replacement of (a) the first jig, from which the two or more first built-in components have been removed for molding, with (b) the second jig having the two or more second built-in components, for the second fuel tank, placed thereon; and
the at least one feed device performing replacement of the first jig with the second jig includes (a) removal of the first jig from the lifting device; and (b) independently moving the second jig, relative to movement of the first jig, so that the second jig is supported by the lifting device for when the second fuel tank is molded.
