Abstract: Embodiments of the present disclosure relate to a transmission gear and a deceleration mechanism including the same. The transmission gear includes a metal ring; and a plastic gear member integral with the metal ring by injection molding, the metal ring is coaxially wrapped in the plastic gear member and provided with a locating portion for locating the metal ring in an injection mold, the plastic gear member having an outer circumference that is tooth-shaped, and the plastic gear member being formed with an input hole thereon through which an input shaft passes, an outer ring surface of the metal ring being adjacent to the outer circumference, and an inner ring surface of the metal ring having a diameter greater than or equal to that of the input hole. Since almost no shrinkage occurs to the plastic gear member during injection molding, such a transmission gear has good dimensional accuracy, strength and rigidity.
