An injection device includes: a heating cylinder; a screw disposed in the heating cylinder; and a pair of piston cylinder components disposed on two sides of the heating cylinder. The pair of piston cylinder components are installed so that one end portion of each of the pair of piston cylinder components is connected to a mold clamping device, and the heating cylinder and the screw are integrally driven in a direction close to or away from the mold clamping device by expansion and contraction of the pair of piston cylinder components. One of the pair of piston cylinder components is provided with a stop mechanism configured to stop expansion and contraction of the piston cylinder component.
