PROBLEM TO BE SOLVED: To make the shape of a motor flat, while prolonging the service life of a brush so much as possible. SOLUTION: A yoke 11 has a cross-section, consisting of a pair of flat parts 13 and left and right circular arc parts 14. Flat spring-type members 27, whose elastic displacement parts 39 are extended in directions approximately in parallel with both the flat parts 13, while brushes 40 attached to the tips of the parts 39 are brought into contact with commutators and whose base ends are positioned outside between both the flat parts 13, are provided. The base parts 38 are formed so as to be extended in directions perpendicular to both the flat parts 13. Female side terminal parts 30, to which supply side terminals are connected, are provided on the inner circumference sides of the base parts 38.
