    Abstract: To provide a safety joint that can immediately shut off a hydrogen gas flow path at the initial stage when a plug (nozzle side member) comes out of a socket (fueling apparatus side member) to prevent release of outgas. A safety joint (100, 100-1) of the present invention includes: a plug (10) with a flow path (1A) formed inside, a shutoff valve (5) of the plug (10) opens when connected to a socket (20); and the socket (20), a flow path (21A) in communication with the flow path (1A) is formed when connected to the plug (10); and when the plug (10) is disconnected from the socket (20), the flow paths (1A, 21A) of the plug (10) and the socket (20) are shut off, wherein the socket has an opening (21C) that communicates with the flow path (21A) and extends orthogonally to the flow path (21A); when the plug and the socket are connected, a protruding portion (3) of the plug is inserted into the opening; and a socket flow path blocking mechanism (30, 31) is provided to instantly close the flow path (21A) at an initial stage when the plug is disconnected from the socket.

    Abstract: To provide a filling apparatus capable of suppressing radial movement of a rod-shaped member (connecting pin) of a nozzle, and preventing damages and deformations (recesses and so on) from generating on an outer peripheral surface of the connecting pin. A filling apparatus (100) according to the present invention includes: a storage tank for storing hydrogen fuel; a filling nozzle (10) for filling a hydrogen gas from the storage tank through a fuel filling system to an in-vehicle hydrogen filling tank mounted on a vehicle; a rod-shaped member (2: connecting pin) and a main body portion (1) mounted on the filling nozzle (10); a sealing member (3: laminated sealing member) arranged on (a radially outer peripheral portion of the rod-shaped member of) the main body portion (1); a guide member (4: pressing member), projecting radially inward, mounted on a portion separated from an end side of the rod-shaped member (2) (from a receptacle 20 side in an in-vehicle hydrogen filling tank to the fuel filling system); and means for protecting an outer peripheral surface of the rod-shaped member (2) from slide on the guide member (4).
