摘要： A joint structure includes a drive side insertion portion of a drive shaft, a driven side insertion portion of a driven shaft, and a coupling. The coupling includes a drive shaft insertion bore, which receives the drive side insertion portion, and a driven shaft insertion bore, which receives the driven side insertion portion. The drive shaft insertion bore includes a wall surface that engages the drive side insertion portion. The driven shaft insertion bore includes a wall surface that engages the driven side insertion portion. A drive side clearance in the drive shaft insertion bore allows the drive side insertion portion to move in the radial direction. A driven side clearance in the driven shaft insertion bore allows the driven side insertion portion to move in the radial direction.

摘要： 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.
