    • PROBLEM TO BE SOLVED: To provide a liquid medicine quantity adjuster capable of being easily handled and allowing an unskilled user to quickly and accurately adjusting the quantity of liquid medicine inside a syringe to a desired quantity.
      SOLUTION: The liquid medicine quantity adjuster includes a pair of clamping members 2 and 2 for holding a plunger 12, and an elastic member 3 for applying the elastic force to approximate distal ends of the clamping members 2 and 2 to each other. The clamping member 2 is formed so that the width of a part in contact with a cylinder flange 13 and a plunger flange 14 when the plunger 12 is held is approximately the same size as of the distance between the rear end surface of the cylinder flange 13 and the front end surface of the plunger flange 14 when the quantity of the liquid medicine within the syringe 10 is the prescribed quantity.
