PROBLEM TO BE SOLVED: To provide an injection device capable of certainly keeping a nozzle touch position constant even in a case that a heating cylinder is thermally expanded in an injection molding machine wherein a mold clamping direction and the material feed direction of the injection device are different from each other. SOLUTION: The injection device 5 of the injection molding machine 1, wherein a nozzle touch direction P and the material feed direction Q in the heating cylinder 5a of the injection device 5 cross mutually, is supported so as not only to be shakable centering around a shaft 6a but also to be movable in the material feed direction Q. Further, the injection device 5 is supported so as to be movable in the direction parallel to the nozzle touch direction P. The upper part of the chamber part 5b communicating with a nozzle 4 is supported so as to be revolvable centering around a shaft 10a and connected to a nozzle holding bar 12. The nozzle holding bar 12 is made movable in the nozzle touch direction P by operating a nozzle touch cylinder 11. COPYRIGHT: (C)2007,JPO&INPIT
