A fluid transfer system includes a multi-jointed robot which is capable of transferring a vial and a syringe, and a syringe driving apparatus. The syringe driving apparatus includes a cylinder body holder which holds a cylinder body of the syringe, an actuator which pulls and pushes a plunger of the syringe, and a rotation mechanism configured to make the cylinder body holder and the actuator freely rotatable about an axial line intersecting with a center axial line of the syringe.
