- the outer diameter convex portion 7a of the plunger 7 is press-fitted into the inner diameter portion 3b of the syringe 3 so as to be slidable.
- the plunger 7 is made of butyl rubber, which is a soft member, and can be compressed and deformed. Thereby, the chemical solution is prevented from leaking from the gap between the plunger 7 and the inner diameter portion 3 b of the syringe 3. Further, in order to improve the slidability, silicon is applied to the outer peripheral surface of the plunger 7.
- the syringe 3 is made of PP (polypropylene).
- the plunger 7 in front of the piston 8 is fixed to the piston 8 such that the inner diameter concave portion 7 b of the plunger 7 and the front end convex portion 8 a of the piston 8 are rotatable with respect to the longitudinal direction of the syringe 3.

- the operation of the syringe 1 includes three operations: suction, bubble removal, and medication.
- suction the state before the drug solution is sucked from the vial is in contact with the front end surface 3e of the first groove 3d as shown in FIG. That is, the piston set 4 is at the frontmost position.
- the syringe needle set 2 may be removed and replaced with a cap, and sterilized and packaged to be used as a prefilled syringe.
- the bubble removal operation of the chemical solution in the liquid chamber is performed.
- the slider 9 moves forward, the capacity of the liquid chamber is reduced, and the chemical solution is discharged from the tip hole 5a of the needle 5.
- the piston set 4 is further moved forward, the slider 9 comes into contact with the stepped portion (target position contact portion) 3j of the guide portion 3c as shown in FIG. 5, and the piston set 4 does not advance any further. In this state, the bubble removal in the liquid chamber is completed, and no air enters the liquid chamber formed inside the syringe 3 and the injection needle set 2.
- a medication operation is performed.
- the protrusion 8 d of the piston 8 is rotated in the circumferential direction of the syringe 3.
- the piston 8 rotates and the slider 9 moves from the second groove 3g to the first groove 3d, and the piston set 4 can be moved in the longitudinal direction.

Since the user does not pay particular attention to the operation at this time by looking at the scale or the like, the volume of the liquid chamber can be set to the target volume with a simple operation. Further, skill is not required for this work, and the volume of the liquid chamber can always be set to the target volume regardless of which user handles the syringe 1.
- the distance between the rear end surface 3h of the guide portion 3c and the step portion 3j is always constant. That is, since the range in which the slider 9 moves from the position where the suction is completed to the position where the bubble removal is completed is constant, the amount of the chemical solution discharged during the bubble removal operation is always constant. Therefore, by appropriately setting the distance between the rear end surface 3h and the stepped portion 3j, an appropriate amount of the chemical solution can always be used for removing bubbles. Conventionally, an excessive amount of chemical solution may be discarded in order to ensure bubble removal, and the chemical solution has been wasted. However, according to the syringe 1 which concerns on a present Example, a chemical
