Piping member and fluid transport device

A pressure vessel includes a vessel body, a first rib and a second rib. The vessel body includes a first surface and a second surface. The first rib projects in a second direction from the first surface and extends in a first direction. The second rib provided in series with the first rib, projects in the first direction from the second surface, and extends in the second direction. A width in the second direction of the internal space is smaller than a width in the first direction of the internal space. A maximum value of a projection amount of the second rib from the second surface to the outside of the vessel body in the first direction is smaller than the maximum value of a projection amount of the first rib from the first surface to the outside of the vessel body in the second direction.
