PROBLEM TO BE SOLVED: To provide an apparatus for assembling a syringe with a plunger rod, capable of correctly controlling the degree of screwing a plunger rod in a gasket.SOLUTION: An upper end of a plunger rod supported by a plunger rod support section is brought into contact with a lower end of a weight supported by a weight support section to enable a mating means on the mutual ends to mate with each other, thereby regulating the horizontal rotation of the plunger rod by a rotation regulating means, the weight support section comes close the plunger rod support section to mate both the mating means and the horizontal rotation of the plunger rod is regulated by the rotation regulating means, the plunger rod support section comes close to a syringe support section while keeping the mating state of both the mating means, the plunger rod is inserted into the syringe and then is separated from the plunger rod support section, and the syringe is horizontally rotated while pressing the screw of the plunger rod into the screw hole of the gasket by the load of the weight. |
