Abstract

A syringe attachment/detachment mechanism enables a syringe to be easily attached to and detached from a discharge device without causing twisting of a tube, and enabling the syringe and an adapter to be fixedly held in a desired orientation. In the syringe attachment/detachment mechanism and the device provided with the mechanism, the mechanism being adapted for a discharge device to which a syringe including an attachment part and an upper connection part is attached through screwing, the attachment part includes an inner cylindrical portion having a small-diameter opening, an outer cylindrical portion surrounding the inner cylindrical portion, and a screw portion. The attachment/detachment mechanism includes a support member including a cylindrical insertion portion into which the inner cylindrical portion is inserted, and having a channel formed therein for communication between the small-diameter opening and a nozzle of the discharge device. A rotation member includes a screw portion.
