<P>PROBLEM TO BE SOLVED: To provide a reaction torque actuator of a steer-by-wire steering device, which enables size and weight reductions and achieves steering feeling without uncomfortable feeling. <P>SOLUTION: This reaction torque actuator generates the steering reaction force at a steering wheel in a steer-by-wire steering device in which steering is performed by the steering wheel that is not mechanically coupled to a steering shaft for turning. The reaction torque actuator is provided with a motor 2 which is a source of generation of the steering reaction force, a deceleration mechanism 3 which transmits, as the reaction torque, the output of the motor 2 to an operation shaft 1b of a steering wheel 1, and a torque damper 5 which reduces fluctuations in the reaction torque transmitted to the operation shaft 1b. The motor 2, the deceleration mechanism 3, and the torque damper 5 are connected being arranged coaxially with the operation shaft 1b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
