Abstract

A piston adapter has a flange holding mechanism mounted on a distal end thereof for releasably holding a piston flange of a piston of a rodless syringe, a manual operating member disposed on a tip end of the piston adapter for being manually operated, and an interlink mechanism for releasing the flange holding mechanism from the piston flange in conjunction with manual operation of the manual operating member. After the piston adapter is mounted on the piston of the rodless syringe and inserted into the cylinder thereof, the flange holding mechanism can be released from the piston in the cylinder by manually operating the manual operating member near the tip end of the piston adapter which is exposed from the cylinder. Even when the piston adapter that is mounted on the piston of the rodless syringe is pressed into the cylinder, the piston adapter can easily be removed from the rodless syringe.
