摘要： An injector comprises a cylindrical barrel, a movable body housed in the barrel, and a plunger coming into separable contact with the movable body. The movable body includes a main body having an outer diameter smaller than an inner diameter of the barrel, a disk-shaped seal body disposed on the main body and including an outer circumferential end brought into close contact with an inner circumferential surface of the barrel, and at least one projecting portion projecting from the main body toward the inner circumferential surface of the barrel. A distance from a central axis of the movable body to a leading end of the at least one projecting portion is smaller than a half of an outer diameter of the seal body.
