Abstract: The disclosure provides a motor with a deceleration mechanism capable of suppressing disengagement of gears even when a large external force is applied to an output shaft. A backup member 70 maintaining engagement between a pinion gear 61 and a helical gear 62 is provided on a side of the pinion gear 61 opposite to the side of the helical gear 62 in a gear case 20. Thus, even when a large external force is applied to the output shaft, disengagement of the gears (disengagement of the pinion gear 61 and the helical gear 62) can be suppressed. Therefore, damage to the pinion gear 61 and the helical gear 62 (deceleration mechanism 60) can be prevented for a long period of time, and consequently the life of the motor 10 with the deceleration mechanism can be extended.
