Abstract
A brush device has a brush that slides against an outer circumferential surface of a cylindrical rotor. The brush device includes a base member, a terminal retained by the base member, an electric wire, which connects the brush to the terminal, and a cylindrical brush holder. The brush holder is located on the base member. The brush holder has a holder axis, which extends along the radial direction of the rotor. The brush is accommodated in and retained by the brush holder and is movable along the holder axis. The brush holder has an opening portion, which is formed at the outer portion of the brush holder with respect to the radial direction of the rotor. The opening portion permits the brush to pass along a direction perpendicular to the holder axis.
