Abstract:
The present invention improves the feeling in use when a finger is hooked on a finger grip. This syringe is provided with a cylinder 22, a syringe needle 24, a finger grip 30, and a plunger rod 32. The finger grip 30 is provided with a cylindrical portion and a pair of finger hook portions. The finger hook portion has an inclined curved surface 70 and an end-side curved surface 72. The inclined curved surface 70 is disposed on a side, of a side surface of the finger hook portion, connected to the cylinder 22. In the inclined curved surface 70, the inclination of a base-side region with respect to the center axis of the cylindrical portion is gentler than the inclination of an end-side region with respect to the center axis of the cylindrical portion. The end-side curved surface 72 is disposed at the boundary between the end of the finger hook portion and the inclined curved surface 70. The end-side curved surface 72 extends along the boundary.
