Abstract
An electric motor structure is shown in which a yoke supporting an armature shaft is fixedly secured to a bracket with set bolts passing through the yoke in the axial direction and in which the distances between a pair of brushes and a pair of internal terminals connected thereto are substantially equal to each other. In a base unit, set bolt through holes for allowing the penetration of a pair of set bolts and a pair of brush holders are disposed on diameter lines perpendicular to each other, and further, a pair of internal terminal plates are disposed to straddle the outer circumference of one set bolt. The inserting tip portion of a coupler unit equipped with external terminal plates electrically connected to the internal terminal plates is branched into two sections. When the coupler unit is connected to the internal terminal plates the set bolt is positioned between the branched sections of the coupler unit.
