  • Electric power steering device
    Patent number: 5482127
    Abstract: A power transmission device, having a frictional face and a pressure member pressed to the frictional face, is provided between the rotary shaft of a motor and a reducing mechanism of an electric power steering device, so that the power transmission is achieved utilizing a frictional force generated between the frictional face and the pressure member, before the output torque of the motor is amplified by the reducing mechanism. Consequently the power transmission device can be made simple and compact in configuration, as it is not necessary to increase the pressing force of the pressure member nor to increase the area of the frictional face.
