<p>An injector adapted such that, when a pusher is engaged with a Luer section, medicinal liquid remaining in a cavity of the Luer section is sealed by a gasket to prevent the medicinal liquid from flowing back into an outer tube. The Luer section has a Luer peripheral wall for covering around the cavity and formed as a tube body having no window hole. An engaging claw is mounted to the inner wall surface of the Luer peripheral wall and has elastic flexible claws protruding from the inner peripheral wall of the cavity toward the center of the cavity. When an engaging projection of the pusher engages with the engaging claw, an opening in the rear of the cavity is closed by the front surface of the gasket, so that liquid remaining in the cavity does not flow into the outer tube.</p> |
