<p>A syringe (1) comprises a cylinder (12) and a plunger (16), and the plunger (16) includes multiple projections (70) provided along an axial direction of a shaft (62). The projections (70) adjacent to each other in the axial direction of the shaft (62) are arranged out of phase with each other in a circumferential direction of the shaft (62). A stopper (80) is disposed on a base end of the cylinder (12) and comprises an axial space part (84) into which the shaft (62) is retractably inserted, an abutting part (90) which abuts the projections (70) when the plunger (16) is advanced, and a notch part (86) which is formed in a position that is out of phase with the abutting part (90) in the circumferential direction and which allows the projections (70) to pass through.</p> |
