<P>PROBLEM TO BE SOLVED: To provide a motor with a speed reduction mechanism wherein the stress concentration of an output gear on a tooth face is reduced to improve the durability of the output gear. <P>SOLUTION: The motor 10 with the speed reduction mechanism comprises a motor shaft 14 having a worm 15 formed near one end, an intermediate gear 26 having a large-diameter gear 26a meshing with the worm 15 of the motor shaft 14 and a small-diameter gear 26b rotated concentrically and integrally with the large-diameter gear 26a, and the output gear 27 meshing with the small-diameter gear 26b of the intermediate gear 26. At the rotational center of the output gear 27, a cylindrical output shaft 28 has an uneven strip fitting portion 28a formed on the inner periphery side. The uneven strip fitting portion 28a is formed only on the lower side of the inner periphery of the cylindrical output shaft 28. <P>COPYRIGHT: (C)2009,JPO&INPIT |
