Abstract
A geared electric motor 1 used for power window apparatuses, for example, which is provided with an mature 7 having an armature shaft 7a, an output shaft 8 connected with the armature shaft 7a through a worm gear pair (7a7 and 17) and two friction plates 9 and 10 to be in contact with both end faces of the armature shaft 7a. The armature shaft 7a of this motor 1 is prevented from rotation by frictional resistance generating between the friction plates 9, 10 and the armature shaft 7a even if the output shaft 8 is applied with rotatory force.
