<p><P>PROBLEM TO BE SOLVED: To provide a steering device for a vehicle which prevents a driver from having a sense of incongruity caused by an unnecessary steering reaction force. <P>SOLUTION: The steering device is provided with a steering shaft 3 which is connected to a first rotary element of a steering side differential transmission mechanism 13, a turning shaft 5 which is connected to the first rotary element of a turning side differential transmission mechanism 14, a reaction force motor which generates reaction torque given to a steering part and is connected to a second rotary element of the steering side differential transmission mechanism 13, a turning motor which generates a turning force for turning a turning wheel and is connected to the second rotary element of the turning side differential transmission mechanism 14, a rotation transmission shaft 18 which connects a third rotary element of the steering side differential transmission mechanism 13 to a third rotary element of the turning side differential transmission mechanism 14, and a lock mechanism 15 which interrupts the transmission of a force from the steering part to the turning wheel by fixing the rotation of the rotation transmission shaft 18 and executes the transmission of a force from the steering part to the turning wheel by making the rotation of the rotation transmission shaft 18 free. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
