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 form 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 plunger (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 prevented by a seal member formed of the molten metal solidified in a rather softened state.
