Abstract
A plunger rod useful for sliding a piston inserted in a syringe barrel has a threaded portion formed at an end of the plunger rod to attach the piston on the plunger rod and a flange formed at an opposite end of the plunger rod. The threaded portion and the flange are integrally connected together by a cylindrical member having an outer diameter such that the cylindrical member can be inserted with contact slidability in the syringe barrel, for example, an outer diameter equal to or slightly smaller than an inner diameter of the syringe barrel.
