Abstract: An LNG filling apparatus that can safely fill LNG in LNG vehicles. A filling apparatus 1 for filling LNG in an in-vehicle tank, the apparatus 1 having a housing 2, a recovery hose 41 and a filling hose 51 separately led from the housing, a recovery mechanism 4 for recovering a natural gas from the in-vehicle tank via the recovery hose, and a filling mechanism 5 for filling LNG to the in-vehicle tank via the filling hose. Separately leading the recovery hose and the filling hose from the housing with these hoses in close proximity to each other allows a range capable of filling that is the overlap range between a connectable range of the recovery hose and a connectable range of the filling hose to be enlarged. A single hose led from the housing can be used for both of the recovery of the natural gas and the filling of the LNG, which prevents tangle of hoses with each other, and enables to fill the LNG in the in-vehicle tank safely.
