摘要： An object is to propose a fluid handling device for liquid hydrogen that prevents evaporation of liquid hydrogen, and moreover affords excellent heat insulation without liquefying oxygen in the vicinity. In a fluid handling device for liquid hydrogen, piping sections (1) have a heat insulation structure, a swivel joint section (2) is configured with helium gas sealed into a boundary relative-rotation section (6) between an outer ring section (3) and an inner ring section (4) with a bearing section (5) interposed, and moreover, between an outside-air-contacting wall section (7) that is in contact with the outside air and a liquid-hydrogen-contacting wall section (8) that is in contact with liquid hydrogen, a vacuum section (9) extends in the axial direction and moreover a heat-conducting extended path section (10) is provided with one end connected to the outside-air-contacting wall section (7) and the other end connected to the liquid-hydrogen-contacting wall section (8), extending the heat conduction distance between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8), and reducing heat conductivity between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8).
