Zusammenfassung:A medicinal solution administration device (10) includes a drive unit (U) that biases a gasket (106) of a syringe (16) by a plunger (82) along with movement of a needle cover (14) in a proximal direction. The drive unit (U) includes a locking mechanism (R) that blocks movement of the plunger (82) in a distal direction in an initial state and allows the plunger (82) to move in the distal direction along with the movement of the needle cover (14) in the proximal direction. A proximal end of the needle cover (14) and the drive unit (U) are connected to each other in an axial direction by a coupling mechanism (19).
