The present invention relates to a life saving device and, more specifically, to a life saving device which simplifies and lightens a structure for supporting a muster station and a lifeboat davit by dividing the structure into top and bottom structures. The new support structure of the life saving device according to the present invention reduces a load by dispersing the stress of the support structure and stably supports the muster station and the lifeboat davit by inhibiting deformation and buckling. The life saving device comprises: a lifeboat davit which is arranged to be separated from the outer wall of a hull; and top and bottom support structures which support the top and bottom of the lifeboat davit to the hull, respectively.
