Abstract

PURPOSE:To prevent a motor from being reversely driven due to a steering force when the motor fails, by disposing a viscous coupling unit in an auxiliary steering force transmission system extending from the motor to a steering shaft. CONSTITUTION:A steering shaft 2 is coupled to a wheel shaft 3 provided with a worm wheel in the intermediate section thereof. A worm 18 fitted on a worm shaft 11 is meshed with the worm wheel 4. A motor casing 19 is secured to a gear casing 6 by means of bolts 20. A viscous coupling unit 200 is secured to one end part of the worm shaft 17. The viscous coupling unit 200 is coupled with a motor shaft 29 through a coupling 25 which is secured to the viscous coupling unit 200.
