    • A steering apparatus for vehicle comprises a steering shaft including a first portion connected to a steering member and a second portion connected to steerable wheels; a transmission ratio variable mechanism capable of varying a transmission ratio as a ratio of a steered angle of the steerable wheels to a steering angle of the steering member; and a reaction-force compensation motor for compensating a steering reaction force of the steering member caused by the operation of the transmission ratio variable mechanism. The transmission ratio variable mechanism includes a differential mechanism for differentially rotatably interconnecting the first and second portions; and a differential-mechanism motor for driving the differential mechanism. Both an axis of a rotary shaft of the differential-mechanism motor and an axis of a rotary shaft of the reaction-force compensation motor are aligned with an axis of the steering shaft.
    • 用于车辆的转向装置包括转向轴,该转向轴包括连接到转向构件的第一部分和连接到可转向轮的第二部分; 传动比可变机构,其能够将传动比改变为可转向轮的转向角与转向构件的转向角的比率; 以及用于补偿由变速比可变机构的操作引起的转向构件的转向反作用力的反作用力补偿电动机。 传动比可变机构包括差速机构,用于使第一和第二部分可差动地互连; 以及用于驱动差动机构的差速机构马达。 差速机构马达的旋转轴的轴线和反作用力补偿马达的旋转轴的轴线与转向轴的轴线对准。
