Document Type and Number:
Japanese Patent JP2021105408
Kind Code:
A
Abstract:
To provide a geared motor capable of improving concentricity between a motor body and a planetary gear mechanism.SOLUTION: A geared motor includes: a motor body 2 having a shaft 29 rotating around a central axial line; a slide bearing 41 which is fixed to the motor body and rotatably supports the shaft; and a planetary gear mechanism 30 connected to an end part on one side in an axial direction of the shaft. The planetary gear mechanism has: a Sun gear 33a rotating around the central axial line together with the shaft; a plurality of planetary gears 33b engaging the Sun gear; a carrier 31 supporting the plurality of planetary gears so that it can revolve around the central axial line; and a cylindrical gear case 35 surrounding the plurality of planetary gears from outside in a radial direction of the central axial line. An inner peripheral surface of the gear case is provided with: an internal tooth gear 36a engaging the plurality of planetary gears; and an engaging surface 36b which is positioned on the other side in an axial direction of the internal tooth gear and is engaged with an outer peripheral surface of the slide bearing.SELECTED DRAWING: Figure 2
