PROBLEM TO BE SOLVED: To provide a new injector capable of quantitatively spouting which can be appropriately used in accordance with various uses such as medical supplies, cosmetics and adhesives and a user's interest.;SOLUTION: A syringe 110 includes a rotatable ring member 150 with a projecting part 151 on its inside. Respective plungers 131 have a plurality of restricting parts 133 for restricting amounts of strokes by placing intervals ΔC along the plunger axis, coming into contact with the projecting part 151 accompanied with pushing-in of a composite plunger 130. When the ring member 150 is rotatably operated to allow the pushing-in of the composite plunger 130, the restricting parts existing on the back end side from the plunger than the projecting part 151 in advance align with the projecting part 151 and the restricting part 133 restricts the amount of stroke accompanied with pushing-in of the plunger 130 thereafter. Successively, it is repeatedly arranged so that when the ring member 150 is rotatably operated to allow the furthermore pushing-in of the plunger 130 to shift the projecting part 151, the restricting parts on the plunger back end side more than the projecting part 151 in advance align with the projecting part 151, and the amount of stroke accompanied with the pushing-in of the plunger 130 thereafter is restricted.;COPYRIGHT: (C)2009,JPO&INPIT
