Abstract
In a normal state, a reaction force actuator () applies an operation reaction force to an steering member () through a planetary gear mechanism (). When failure occurs in a steering actuator (), the reaction force actuator () is turned off, and a plunger () locks the rotation of one element () which is connected to the reaction force actuator (), in the planetary gear mechanism (). In turn, a manual steering mode is set up in which a rotation of the steering member () is transmitted to a pinion gear () at a transmission ratio of the carrier () holding planetary gears () and a sun gear ().
