Abstract
An electric power steering apparatus includes a steering shaft for transmitting a steering force of a steering handlebar to a wheel and an upper bearing provided at a location upward from a vehicle body frame so as to rotatably support an upper part of the steering shaft. A lower bearing is provided at a location downward from the vehicle body frame, so as to rotatably support a lower part of the steering shaft. A torque sensor detects a torsional torque applied to the steering shaft. An electric motor imparts a steering force to the steering shaft based on the torsional torque detected by the torque sensor. The electric motor is mounted to the steering shaft between the upper bearing and the lower bearing, while the torque sensor is mounted to the steering shaft at place upward from the upper bearing.
