1. A high-pressure tank liner manufacturing device for welding end surfaces of a pair of liner halves arranged to face each other into a unitary piece, the device comprising:
a heater arranged between the end surfaces of the pair of liner halves, facing each other, to heat and melt the end surfaces of the pair of liner halves;
a heater transportation mechanism configured to slidably move the heater between a waiting position for the heater, away from the pair of liner halves, and a heating position for the heater set between, for heating, the end surfaces of the pair of liner halves;
a drive mechanism configured to drive at least one of the pair of liner halves so as to cause the pair of liner halves to be relatively moved closer to each other or away from each other; and
a parallelism adjustment mechanism configured to adjust parallelism of the end surfaces of the pair of liner halves in accordance with the heater being slidably moved.
