<P>PROBLEM TO BE SOLVED: To provide a syringe capable of discharging a liquid in an accurate quantity by a simple operation. <P>SOLUTION: The syringe comprises a pusher 4 for moving/operating a gasket slidable in a barrel 2 and a stopper 5 for limiting the depth of insertion of the pusher 4 into the barrel 2. The stopper 5 comprises a base part 51, a pair of engagement parts 52a and 52b connected to the base part 51 for selecting the positions on the pusher 4 to be fixed at the positions by the engagement with the pusher 4, and a pair of operation parts 53a and 53b connected to the base part 51 for the operation of releasing the engagement of the engagement parts 52a and 52b with the pusher 4. The engagement of the engagement parts 52a and 52b with the pusher 4 is released as the engagement parts 52a and 52b are relatively separated from each other according to the operation of relatively bringing the operation parts 53a and 53b close to each other. When the operation for the operation parts 53a and 53b is released, the engagement parts 52a and 52b are engaged with the pusher 4 as the engagement parts 52a and 52b are relatively brought close to each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
