Abstract
A brushed motor includes a shaft, an armature around the shaft, a commutator on one side of the armature in an axial direction, a brush card on one side of the commutator in the axial direction, and a housing accommodating a portion of the shaft, the armature, the commutator, and a portion of the brush card. A convex portion positions corresponding to the commutator in the axial direction on a surface of the brush card on one side facing the commutator, which has a main body portion around the shaft and a pin bent from an end of the main body portion on the other side in the axial direction toward an outer side in a radial direction and one side in the axial direction. A distance between the pin and a brush on the brush card is larger than that between the main body portion and the convex portion.
