The life saving raft comprises; a unit body (11) having a air injection portion (14) through which air is injected; a frame work (12) made of springs or rings being installed on the inner side of the unit body (11) in order to keep the unit body (11) in a fixed shape. The unit (11) may have a shape like a pillar and linking means to connect the end parts of the both sides. So this life raft maintains the fixed shape by the frame work (12) even if air leaks from the unit body (11).
