Abstract
One first connector head 21A and one second connector head 22A face each other, in the plane view of a connector terminal assembly 19, with the axial line of an output shaft 12, which is the axial line of the motor rotation shaft of an electric motor, therebetween without being offset from each other. The other first connector head 21B and the other second connector head 22B face each other, in the plane view of the connector terminal assembly 19, with the axial line of the output shaft 12, which is the axial line of the motor rotation shaft of the electric motor, therebetween without being offset from each other.
