Abstract
A multi-chamber syringewhich can be manufactured at a low-cost and high-productivity is provided. The syringeincludes a generally cylindrical barrel, a push memberand a plug, both of which are disposed to fit the inner side surfaceof the barreland slidably on the inner side surface. The plughas a main surfaceprovided with a projectionhaving a topwhich is eccentric to the main surface. When the push memberslides in the direction indicated by Arrow A, the plugcomes under pressure from the side on the open end. When the projectionof the projectionmakes contact with the choked end, the pressure from the side on the open endacts to turn the plugin the direction indicated by Arrow B. This causes a bending deformation in a main bodyand flangesof the plug, to form a first gapand a second gapbetween the inner side surfaceof the barreland the plug
