ABSTRACT:
An improved electric motor having an output shaft which moves in a reciprocating rectilinear motion and in which face contact between confronting axially transverse contact surfaces of stops on the output shaft and a driving member is prevented so as to eliminate the undesirable bite or cutting-in at limits of forward and backward movements of the output shaft.
