Abstract
A composite gear member of the power transmission device is divided into an annular first member and a second member. The annular first member is formed with an output gear. The second member is formed with internal teeth and spline-coupled to an inner portion of the first member. Therefore, the influence of the engagement reaction force generated from the output gear of the first member is decreased by the spline-coupling, and the vibration is reduced.
