<P>PROBLEM TO BE SOLVED: To provide a syringe allowing a zero point adjustment and storing a canula in a barrel. <P>SOLUTION: When a gasket 4 is moved to an advance end for executing the "zero-point adjustment" of the syringe 1, an engagement means 8 incorporated in the gasket 4 is pushed rearward by a second projection 6b formed at the rear end of an inner hub 6 to deform a space S formed inside the gasket 4 and prevent the connection between the gasket 4 and the inner hub 6. On the other hand, when an inner core rod 11 is positioned in an advancement position after using the syringe, the deformation of the space S is prevented and the second projection 6b of the inner hub 6 is engaged and inserted in a first projection 8c of the engagement means 8 to connect the gasket 4 to the inner hub 6 and store the canula 5 inside the barrel 2 along with the inner hub 6. <P>COPYRIGHT: (C)2007,JPO&INPIT |
