摘要：
An electric power steering device including an input shaft to which a steering wheel is connected, an output shaft connected to a wheel side, a torsion bar provided between the input shaft and the output shaft, and a torque sensor that detects steering torque input from the steering wheel. An electric motor is driven in accordance with the torque detected by the torque sensor. A worm wheel is provided on the output shaft to transmit rotation of the electric motor to the output shaft in a housing, wherein a boss of the worm wheel is fitted into an outer circumference of the output shaft, and a bearing fitted into the outer circumference of the boss is supported on the housing.
