    摘要： It is to provide a brush-equipped motor enabled to be used for a long time without performing operations and without interruption even when the brush wears out. When a rotor is caused to perform a turning operation, cam projections similarly start to perform a turning operation. Then, an abutting part, at which each of the cam projections contacts with a spring piece part of a corresponding one of the first brushes, gradually moves to an end of the first brush. Thus, the spring piece part of each of the first brushes is gradually and elastically deformed in a direction in which brush bodies come away from a commutator. When the turning operation continues still more, an end of each of the second brushes comes off a corresponding one of the cam projections, so that the brush bodies thereof contact with the surface of the commutator.

    摘要： A speed changing mechanism for use with an electric rotary tool, an electric press-attaching tool, an automatic screw tightening tool or the like, includes planet gears, a planet gear support plate integrally formed with an internal gear and provided with an external gear formed outwardly of the internal gear. The planet gears are rotatably supported by a second planet gear support plate mounted on a driven shaft and formed with a second external gear. The planet gears are engaged with the interanl gear and a sun gear provided on a one-way clutch. A cylindrical member having an internal gear is slidably fitted with at least one of the first and second external gears. The speed changing mechanism can be set to have a ratio of the rapid rotation speed to the slow rotation speed of 2.5/1 or less.
