Abstract
The adapter includes a housing and a filling nozzle provided in communication with a containing portion in the housing and coming into contact with an end surface of the injection device, in which the injection port of the injection nozzle is formed, when the housing is attached to the injection device. An open end of the filling nozzle is set to be smaller than an inner diameter of the containing portion and larger than the injection port. Of an internal space of the housing from a partial region of the containing portion to the open end, at least a predetermined space being continuous and including the partial region is formed in a manner where an inner diameter of the predetermined space decreases toward a side of the open end. According to this configuration, the injection fluid can be suitably transferred from the outside to a needleless injector.
