Beschreibung
Zusammenfassung:	In an electric power steering device, an actuator generates steering assistance power in response to torque transmitted by a steering shaft, the outer circumference of which is covered by a torque sensor detecting the torque. The rotation of the actuator is transmitted to the steering shaft by a reduction gear mechanism having a driven gear on the steering shaft, and a driving gear which engages with the driven gear. The torque sensor is disposed between the driven gear and the steering wheel. A housing has a portion which covers the steering shaft between the steering wheel and the torque sensor, and a portion which covers the torque sensor. The housing is formed by plastically deforming a single metal pipe.
