Abstract
A gear assembly includes a pair of driving and driven helical gears permanently in meshing engagement with each other to provide a torque transmission therebetween, and an additional plate-like gear formed at its outer periphery with helical teeth the helix angle of which is different from each helix angle of respective teeth of the helical gears and being resiliently deformable in an axial direction. The additional plate-like gear is coaxially and rotatably mounted in place on a hub portion of the driven helical gear and meshed at its two teeth with one tooth of the driving gear such that the additional plate-like gear is resiliently in contact with one end face of the driven gear at a place radially opposite to the meshed portion of the helical gears.
