Abstract: To provide a support structure that can eliminate difficulty of operation due to rigidity of a filling hose and prevent difficulty in removing a filling nozzle from a receptacle after filling. A support structure (100) of the present invention includes a swivel joint (3: the first swivel joint) in a filling hose (2) that connects a filling nozzle (1) and a gas supply pipe of the dispenser (10) (for example, a hydrogen supply pipe), and the swivel joint (3) comprises a nozzle side member (3B) communicating with the filling nozzle (1) side, and a dispenser side member (3A) communicating with the dispenser (10) side, the nozzle side member and the dispenser side member are relatively rotatable, and a high-pressure gas flow path (3AR) formed in the nozzle side member and a high-pressure gas flow path (3BR) formed in the dispenser side member are orthogonal to each other.

Abstract: To provide a filling hose guide device for preventing a plug of a safety joint or a filling hose from being locked in a lower opening of a casing when a safety joint separates, thereby preventing a filling device from falling over and being damaged. A filling hose guide device 100 according to the present invention is characterized in that after a plug 10 connected to a filling hose 61 and a socket 20 provided in a filling device 200 in a safety joint 300 separate when a tensile load above a predetermined level is applied to the filling hose 61, the filling hose guide devices 100 include: a rotatable or deformable member 30A, 30B, with which the filling hose 61 contacts, below the safety joint 300; and a support structure 50, through which the filling hose 61 passes, for supporting the rotatable or deformable member 30A, 30B.
