PROBLEM TO BE SOLVED: To provide a motor with a reduction gear that can reduce weights of an output gear and a driven member engaging with the output gear while securing intensity of the output gear.SOLUTION: A speed reduction mechanism includes: a gear frame attached to the yoke of an electric motor; a support shaft 26 fixed to the gear frame; and a pinion gear rotatably supported to the support shaft 26 and engaged with a sector gear of a wind regulator to drive the wind regulator. In the pinion gear, a through hole 45 into which the support shaft 26 is inserted is formed, and a module m is set to 1.5 or less. In a tooth bottom 44b of the pinion gear, a tooth bottom extension unit 51 that extends the tooth bottom 44b in a radial direction is formed. |
