A bulging apparatus has a heating station, a tube expanding station, a preforming station, and a main forming station. A straight tube as a workpiece is gripped by first holding mechanisms or second holding mechanisms, and delivered between the stations as the first holding mechanisms or second holding mechanisms are displaced. During a preforming process and a main holding process, both the first holding mechanisms and second holding mechanisms can be lifted and lowered vertically and can be moved horizontally.
