PROBLEM TO BE SOLVED: To prevent the displacement of a heating cylinder even if a supporting plate supporting the heating cylinder is thermally expanded by heat transfer from the heating cylinder. SOLUTION: The heating cylinder 2 horizontally supported by a supporting plate 6; a material holder supporting a material R; and a hydraulic cylinder apparatus feeding the material R into the heating cylinder 2 by the advance operation of a plunger and injecting the molten material in the heating cylinder 2 from a nozzle for injection at the tip of the heating cylinder 2 are assembled onto a base 14 in a state where the respective axial centers are arranged on a straight line. The device comprises a supporting mechanism 7 supporting the supporting plate 6 under a state of being dangling in the air, and the supporting mechanism 7 is composed of: a pair of arms 64 projectingly provided on both the sides of the supporting plate 6 outwardly and provided with the faces 65 to be supported located on a horizontal surface S passing through the center O of thermal expansion in the supporting plate 6; and a pair of pillars 70 vertically provided at the confronted positions on the base 14 and provided with supporting faces 72 supporting the faces 65 to be supported in the respective arms 64 freely slidably from the lower part.
