Abstract
To provide a gas supply device capable of suppressing undesirable separation of a separation joint.SOLUTION: A hydrogen gas filling device 1 includes a gas supply pipeline 5 and a hose 6, a nozzle 7, and a separation joint 31 for separating the hose 6 and the gas supply pipeline 5 from each other in emergency, the separation joint 31 having a nozzle side joint 31A, an opposite-nozzle-side joint 31B, a shear pin 31C. The separation joint 31 is separated into the nozzle side joint 31A and the opposite-nozzle-side joint 31B by the fracture of a shear pin 31C when predetermined force is applied between the nozzle side joint 31A and the opposite-nozzle-side joint 31B. The hydrogen gas filling device 1 further includes a desorption regulation device 41 separately from the shear pin 31C, for keeping a state of connection between the nozzle side joint 31A and the opposite-nozzle-side joint 31B.SELECTED DRAWING: Figure 2
