摘要 |
A plunger for a syringe, in which a plunger rod can be prevented by a simple structure from unavoidably falling out of place. The plunger for a syringe includes the plunger rod and a gasket. The gasket is closed at its upper end and has an inner space, and an opening having a diameter smaller than the diameter of the inner space is provided in the lower end of the gasket.
