1. A safety joint, including:
a cylindrical nozzle side member with a flow path formed inside, a shutoff valve of the nozzle side member opening when the nozzle side member is connected to a filling apparatus side member; and
the filling apparatus side member having a cylindrical shape and a flow path formed inside, the filling apparatus side member being connectible to the nozzle side member,
and when the nozzle side member is disconnected from the filling apparatus side member, the shutoff valve of the nozzle side member closes and the flow path of the filling apparatus side member closes, said safety joint is characterized in that:
central axes of the flow paths of the nozzle side member and the filling apparatus side member are arranged orthogonally;
the nozzle side member has a protruding portion with a diameter smaller than a region in which a valve body is housed, and the protruding portion is formed with a through hole that communicates the flow path of the nozzle side member and the flow path of the filling apparatus side member;
the filling apparatus side member has an opening portion into which the protruding portion of the nozzle side member is inserted, the opening portion extending in a direction orthogonal to the flow path of the filling apparatus side member;
the opening portion is provided with a slidable closing member and an elastic member that urges the slidable closing member in a direction that the nozzle side member comes off; and
said safety joint further incudes a closing member holding mechanism holding the slidable closing member at a position separated from the nozzle side member when the nozzle side member and the filling apparatus side member are connected.
