Abstract
A vehicle steering apparatus includes a steering member; a steering shaft connected to the steering member; a torque sensor for detecting a steering torque inputted into the steering member; and an electric motor for generating power that is transmitted to the steering shaft based on the steering torque detected by the torque sensor. The electric motor includes an annular rotor and an annular stator. The annular rotor includes an annular rotor core which coaxially surrounds the steering shaft and is rotatable together with a part of the steering shaft. An annular accommodation space is formed between an outer circumference of the steering shaft and an inner circumference of the annular rotor core, and at least a part of the torque sensor is disposed within the annular accommodation space.
