An electrically-driven dental injector used in orally injecting such an injection liquid as an anesthetic in dental treatment. Electrically-driven dental injectors includes one having a mechanism for disengaging a pinion ( ) from a rack ( ) in order to retract a plunger rod ( ) upon completion of injection; however, it has heretofore been necessary to manually operate the operating part from outside each time. The inventive electrically-driven dental injector is so arranged that the plunger rod can be manually pushed back directly oupon completion of injection without requiring manual operation, and, to this end, the injector comprises a latch mechanism ( ) for engaging/disengaging the ring gear ( ) of a planetary reduction gear ( ) with/from a casing ( ), and an operating rod ( ) extending through a support member ( ) and functionally cooperating with the latch mechanism ( ).
