Abstract
A power transmission device of a motor-driven power steering system is provided which comprises a driving gear mounted on the outside of a shaft transmitting a force given from a steering wheel to a steering mechanism and rotatable about the shaft, a first connecting member including at least one gear for coupling the driving gear and a driving shaft of an electric motor, a second connecting member coupled to one out of the shaft and the driving gear, and a buffering member having elasticity coupled to the other out of the shaft and the driving gear and to the second connecting member. Preferably, the second connecting member has a cylindrical portion secured on the outside of the shaft and projections, and the driving gear has holes for receiving the buffering member and the projections.
