Abstract
A gear assembly wherein transmission efficiency is enhanced by a simple treatment is provided. The gear assembly includes a plurality of gears to transmit torque of a prime mover to an output member. Tooth surfaces of a first gear rotated at a highest speed are individually finished into a plateau surface, and a parameter representing a surface roughness of each of the plateau surface is smaller than those of the tooth surfaces of the other gears.
