Patent attributes
To provide a filling device capable of preventing that a filling nozzle is detached before depressurization is performed after filling, preventing a seal structure from deteriorating, and decreasing a risk that hydrogen gas leaks. In filling devices (100, 101) including a storage tank for storing hydrogen fuel, filling nozzles (10, 11) for filling hydrogen from the storage tank through a fuel filling system including a dispenser (60), a filling hose (45) and so on to an in-vehicle hydrogen filling tank mounted on a vehicle, and a clutch mechanism (12) for maintaining a connected state between the filling nozzles (10, 11) and a vehicle side filling port (20), and are characterized in that the clutch mechanism (12) comprises a clutch (4) for fitting the vehicle side filling port (20) by a recess/projection when the clutch (4) connects the vehicle side filling port (20), and a lever (5) for maintaining the fitting between the clutch (4) and the vehicle side filling port (20) by the recess/projection by moving in a direction that the clutch (4) and the vehicle side filling port (20) are connected with each other, the lever (5) having an engaging portion (5B), when hydrogen is filled, the clutch (4) moves outward in a direction vertical to the connecting direction via a contacting portion between the clutch (4) and the vehicle side filling port (20) and engages with the engaging portion of the lever (5).
