A yoke housing includes a tubular case and a flange. The tubular case is formed from a metal sheet in a drawing process. The flange is formed at an end of the tubular case. The flange has a width in the lateral direction that is equal to the outer diameter of the tubular case. The flange has a base including beads and a thick portion. Each of the beads is formed by compressing the base. A portion of the base in which the beads are not formed defines a thick portion. The thick portion is located at a middle portion of the flange in the lateral direction. The beads are located on opposite sides of the thick portion in the lateral direction.

A motor includes a rotation shaft, a commutator, power supply brushes, and a brush holder. The brush holder includes an opposing portion that faces an end face of the commutator in an axial direction, a bearing holder, and a diffusion stopper. The diffusion stopper is arranged in a portion of the opposing portion located toward the outer side in the radial direction from the bearing holder and limits the diffusion of abrasion powder of the power supply brushes. The diffusion stopper is projected toward the commutator in the axial direction or recessed in the axial direction.
