<P>PROBLEM TO BE SOLVED: To provide a chemical injecting device wherein a chemical syringe can be easily attached/detached by one hand. <P>SOLUTION: When a cylinder flange of the chemical syringe is inserted from the top into flange holding members 111 which are arranged at an opened position by the urging of a hold-urging mechanism, the flange holding members 111 are displaced to a closed position by the pressing. Therefore, a close-holding member 116 is engaged with the lower end of the flange holding members 111 by the urging of a close-urging mechanism, and the chemical syringe is fixedly held. When the close-holding member 116 is displaced downward from this state by a manually operating member 118, a pair of the flange holding members 111 are displaced to the opened position by the slipping off of the close-holding member 116 from the lower end, and the chemical syringe is placed under a state wherein the chemical syringe can be taken out upward. <P>COPYRIGHT: (C)2004,JPO |
