In an injection apparatus, a guide screw shaft of a body section (20) and a screw of an operation knob (34) of a movable section (30) allow the movable section (30) to move relative to the body section (20). An ampule (7) is radially inserted into a ampule holding portion (36) of the movable section (30) and temporarily held by means of an elastic blade (36a) and at the same time, a flange (75) of the ampule (70) is inserted into a flange insertion portion (38). When the operation knob (34) is rotated, the movable section (30) moves toward the body section (20) together with the ampule (70). A guide sleeve formed in the body section (20) is inserted into a syringe (77) of the ampule (70). An operation knob (50) is rotated to set the feeding amount of a piston rod, and the operation knob (50) is pressed to perform an injection. When a release button (40) is pressed, the piston rod is returned to an initial position. This construction allows the ampule (70) to be easily mounted on the injection apparatus and the state of medicine in the ampule (70) to be easily seen.
