1. A connector for a fluid, comprising: a cylindrical section configured to let a fluid pass therethrough, which has a male lure taper at one end portion of its outer peripheral surface;
a connection member detachably attached to the cylindrical section, which is used in connecting with another member having, on its inner peripheral surface, a female lure taper, wherein the cylindrical section has, on an outer peripheral surface of its other end, an annular recess, wherein the connection member comprises an inner cylinder member coaxial with the cylindrical section, which is mountable to the cylindrical section in such a manner that the cylindrical section is at least partially accommodated inside the inner cylinder member, and an outer cylinder member coaxial with the inner cylinder member, which is configured to be fit together with and mounted to the inner cylinder member from one end of the inner cylinder member in such a manner that the inner cylinder member is at least partially accommodated inside the outer cylinder member, wherein the inner cylinder member comprises an inner cylinder body having on its inner peripheral surface a female screw, and an engagement plate configured to engage with the recess and connects with the inner cylinder body at a position farther from the one end of the inner cylinder member than the female screw is from the one end, relative to an axial direction of the cylindrical section, wherein the inner cylinder member is provided with a plurality of slits which are arranged radially with respect the axial direction, and which extend from the engagement plate to a part of the inner cylinder body so as to divide the engagement plate into a plurality of engagement pieces, and partially divide the inner cylinder body into segments corresponding to the plurality of engagement pieces, wherein a movement of the inner cylinder member in an axial direction relative to the syringe main body is restricted by engagement of the recess with the engagement plate, wherein the plurality of engagement pieces are able to displace in diameter expansion directions while the outer cylinder member is not mounted to the inner cylinder member, and wherein, while the outer cylinder member is mounted to the inner cylinder member, the inner peripheral surface of the outer cylinder member contacts the outer peripheral surface of the inner cylinder member within a range relative to an axial direction, in which range the plurality of slits are formed, thereby restricting displacement of the plurality of engagement pieces in the diameter expansion directions. |
