An injection device (1) allowing the efficient supply, fusing, and injection of light metal materials, particularly magnesium alloy materials, and the facilitated maintenance and inspections thereof, comprising a fusing device (10), a plunger injection device (20), and a connection member (18) communicating these devices with each other, wherein the plurality of light metal materials are inserted into a fusing cylinder (11) or (111) in the for m of billets (2), the inserted billets (2) are molten starting at the forward portion thereof and changed into molten metal for several shots, the molten metal is extruded by a billet inserting device (50) through billets (2) themselves, passed through the connection member (18), and metered by an injection cylinder (21), the measured molten metal is injected by the plunge r (24) of a plunger drive device (60), and the backflow of the molten metal in the fusing cylinder (11) or (111) and the injection cylinder (21) is prevent ed by a seal member formed of the molten metal solidified in a rather softened state.
