  • Patent number: 6896090
    Abstract: In a normal state, a reaction force actuator (20) applies an operation reaction force to an steering member (2) through a planetary gear mechanism (6). When failure occurs in a steering actuator (12), the reaction force actuator (20) is turned off, and a plunger (13) locks the rotation of one element (18) which is connected to the reaction force actuator (20), in the planetary gear mechanism (6). In turn, a manual steering mode is set up in which a rotation of the steering member (2) is transmitted to a pinion gear (14) at a transmission ratio of the carrier (16) holding planetary gears (17) and a sun gear (15).
