PROBLEM TO BE SOLVED: To prevent a syringe from turning round and a tube from being twisted by setting a flange to a syringe along its longitudinal direction and inserting the flange into a shallow groove of a concave part for insertion at a syringe driving mechanism. SOLUTION: The automatic injecting device is composed of a syringe 1 and a box-shaped syringe driving device 2 that mounts actuator 21 beneath the part to which the syringe is attached. The automatic injecting device consists of board-shaped jaw 10 attached to the syringe 1 toward the longitudinal direction of the syringe 1 and the shallow groove 20a of a concave part for insertion that is made at the syringe driving device 2 while the board-shaped jaw 10 is inserted into it. When the syringe 1 is attached to the syringe driving device 2, the jaw 10 can prevent the syringe 1 from being turning round. |
