Title:
SPEED REDUCER-PROVIDED MOTOR, WIPER DRIVING DEVICE, AND POWER WINDOW DEVICE
Document Type and Number:
Japanese Patent JP2019187028
Kind Code:
A
Abstract:
To provide a speed reducer-provided motor, a wiper driving device, and a power window device, in which downsizing can be achieved irrespective of a reduction ratio and a product cost can be reduced.SOLUTION: A speed reducer-provided motor includes a motor 2 having a rotary shaft 14, and a speed reduction mechanism 3 that reduces a speed of rotation of the rotary shaft 14 and outputs the rotation to an output shaft 34. The speed reduction mechanism 3 includes a magnetic speed reduction gear 31 to which the rotation of the rotary shaft 14 is inputted, and a worm speed reduction gear 32 that reduces the speed of the rotation outputted from the magnetic speed reduction gear 31. The magnetic speed reduction gear 31 is formed by disposing two magnetic gears 51, 52 to face each other in a radial direction, and includes a magnetism detection substrate 33 that detects a change in a magnetic flux of the second magnetic gear 52.SELECTED DRAWING: Figure 2
