<P>PROBLEM TO BE SOLVED: To provide a geared actuator which prevents a shaft runout of a motor, thus causing less noise generation. <P>SOLUTION: This geared actuator, decelerating a driving force of a motor mounted in a housing by a plurality of gears, converting it to a prescribed power, and transmitting it to an external, includes a rotating shaft which protrudes from a motor case and supported by a bearing; a first gear fixed to the rotating shaft; a motor which rotates with the rotating shaft, and which has a ring-shaped magnet positioned so that the center of the ring meets the axial center of the rotating shaft; and a yoke which has a second gear engaged and interlocked with the first gear from a radial direction of the rotating shaft, and formed out of magnetic material which attracts the magnet so that the rotating shaft may be energized toward the radial direction on an opposite side to the position of the second gear, should be provided in the housing. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
