。 A forward/reverse rotation type general-purpose electric operation consisting of an electric motor section, a reducer section that is connected to the electric motor and reduces its rotation with a gear, and a rotation angle control section that limits the rotational range of the output shaft of this reducer section. In the machine, protrusions and depressions are provided on the upper and lower surfaces of a cam for operating a limit switch used in the rotation angle control section, the phases of which are shifted by the required operating angle, and a plurality of the cams are assembled so that the protrusions and depressions fit into each other. A general-purpose electric operating machine characterized by making it possible to simultaneously perform restriction adjustment of forward and reverse rotation angles.
