<P>PROBLEM TO BE SOLVED: To provide a syringe capable of discharging the accurate amount of liquid by a simple operation. <P>SOLUTION: The syringe is provided with an outer cylinder, a gasket, a pusher 4 for moving the gasket, and a stopper 5 installed so as to be slid along the longitudinal direction of the pusher 4 and adjusted at a desired position on the pusher 4. The stopper 5 is provided with a stopper main body 51 and brake parts 52. When the base end side of an operation member 6 is pressurized to the pusher 4, a wedge part 612 is inserted between the brake parts 52 and pushed so as to be opened in the direction of separating from each other. Thus, the respective brake parts 52 are brought into press contact with the pusher 4 and the stopper 5 is fixed to the pusher 4. When the pusher 4 is pressurized in a tip direction in the state, the tip surface 514 of the stopper 5 abuts on the base end part of the outer cylinder, so that the insertion depth of the pusher 4 into the outer cylinder is controlled and thus the set amount of a chemical is discharged from a tip part. <P>COPYRIGHT: (C)2004,JPO |
