<P>PROBLEM TO BE SOLVED: To provide a chemical injecting device by which a chemical syringe can be easily attached/detached by one hand. <P>SOLUTION: A holding shaft is press-joined by a shaft press-joining mechanism to the holding arm of a flange holding member 111. By engaging the holding shaft with a first recessed groove of the holding arm, a pair of the flange holding members 111 are opened upward, and are held at an opened position wherein a cylinder flange 203 of a chemical syringe 200 is inserted. By engaging the holding shaft with a second recessed groove of the holding arm, a pair of the flange holding members 111 are held at a closed position wherein the cylinder flange 203 is held from both sides. Therefore, the chemical syringe 200 can be easily attached/detached to/from this chemical injecting device 100, and can be surely held. <P>COPYRIGHT: (C)2004,JPO |
