Abstract

A geared motor includes a motor and a reduction drive. The reduction drive includes a gear housing, a speed reduction-output member, and a restriction portion. The gear housing includes a support shaft. The speed reduction-output member includes a reduction gear, an output gear meshed with an input member, and an accommodation recess. The speed reduction-output member is rotationally supported by the support shaft. The restriction portion is configured to restrict movement of the speed reduction-output member relative to the support shaft. The restriction portion is located between an outer circumferential surface of the support shaft and an inner circumferential surface of the accommodation recess. The restriction portion is located in an axial direction of the support shaft at a position that differs from a portion where the speed reduction-output member abuts in a radial direction against the input member.

Claims (17)

1. A geared motor comprising:

a motor; and

a reduction drive coupled integrally to the motor,

wherein the reduction drive includes a gear housing, a speed reduction-output member, and a restriction portion, wherein

the gear housing includes a support shaft,

the speed reduction-output member includes a reduction gear that reduces a speed of rotation produced by the motor, an output gear that is rotatable integrally with the reduction gear and meshed with an input member, and an accommodation recess,

the speed reduction-output member is fitted to the support shaft and rotationally supported by the support shaft,

the restriction portion is configured to restrict movement of the speed reduction-output member relative to the support shaft, wherein the restriction portion is located between an outer circumferential surface of the support shaft and an inner circumferential surface of the accommodation recess, and

the restriction portion is located in an axial direction of the support shaft at a position that differs from a portion where the speed reduction-output member abuts in a radial direction against the input member.

2. A power window device comprising:

the geared motor according to claim 1 ; and

a window body,

wherein the power window device is configured to open and close the window body with a wire that runs around the input member.

3. The power window device according to claim 2 , wherein the speed reduction-output member of the geared motor includes a large-diameter portion,

the large-diameter portion has a larger diameter than the output gear,

the large-diameter portion is located between the reduction gear and the output gear, and

the input member is configured to abut in the radial direction against the large-diameter portion.
