Abstract
In a motor having a motor unit and a speed-reducing unit, a brush holder is sandwiched between a yoke housing of the motor unit and a gear housing of the speed-reducing unit. The brush holder includes holder body, joining portion, and connector portion. The holder body is formed with a first opening being open in the yoke housing. The joining portion is formed with a cylindrical portion extending in a direction same as the opening direction of a connector recessed portion of the connector portion. A second opening is formed on an end surface of the cylindrical portion. The first opening communicates with the second opening through first and second communication holes, so that pressure difference between the inside and outside of the yoke housing and the gear housing are cancelled.
