  • Patent number: 11316411
    Abstract: This motor includes a yoke, an armature, a brush holder and a ground member. The yoke has the shape of a bottomed cylinder that has an inner surface to which a magnet is affixed. The armature is contained within the yoke. The brush holder is arranged in an opening of the yoke, and holds a feed brush for supplying an electric current to the armature, and a bearing that axially supports a rotary shaft of the armature. The ground member is in contact with the bearing and the yoke. The ground member is affixed to a ground terminal that is held by the brush holder.

  • Patent number: 11228230
    Abstract: This motor includes a yoke housing, a brush holder, a housing case and a circuit board. The brush holder holds a power supply brush and power supply terminals. The housing case has a board containing recess into which front end portions of the power supply terminals are inserted. The circuit board has terminals which are electrically connected to the power supply terminals within the board containing recess. The power supply terminals have terminal connection parts which linearly extend and are arranged in the board containing recess. The terminals are fork terminals which are electrically connected to the terminal connection parts. With respect to the terminal connection parts, portions closer to the base ends than terminal connected positions, where the terminals are connected, are covered by noise reduction member for reducing noise.

  • Patent number: 9546699
    Abstract: First and second clutches allow first and second tubular output shafts to pivot when a motor generates rotation at a second rotation speed or higher. A third clutch allows a pivot shaft to pivot when the motor rotates at a speed lower than a first rotation speed. A control plate is arranged at a first pivot position, second pivot position, or third pivot position. At the first pivot position, the first and second tubular output shafts are moved to positions in an axial direction allowing first and second rotated members to rotate. At the second pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the first rotated member to rotate. At the third pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the second rotated member to rotate.
