(57) Abstract :
Then is provided a bellows for a pressure vessel that would not rupture due to thermal expansion and contraction, avoiding stagnation
of a raw material. The bellows 40 for a pressure vessel is adapted to realize ring-shaped sealing between an open end 11 of a bottomed
tubular vessel body 10 into which a raw material is caused to flow, and an outer peripheral portion of a dispersion board 30 closing the
open end 11 so as to permit down low of the raw material toward the bottom of the vessel body 10. The bellows 40 is provided with a
flexure portion 41 flexing racially so as to permit thermal expansion and contraction without being depressed for avoiding of
stagnation of the raw material. The flexure portion 41 has a concave curved surface 42 and a convex curved surface 43 which are
continuously formed to have a wave shape.
