A steer-by-wire steering device includes a steering wheel (1) connected with a steering shaft (10), a steering angle sensor (2), a steering reactive force motor (4), and a steering control unit (5a) for controlling a steering shaft drive motor (6) and the steering reactive force motor (4). Provided is a power transmitting mechanism (18) for transmitting the power from the steering shaft drive motor to the steering shaft. A changeover unit (17) for selectively connecting and disconnecting the power is disposed on the way thereof. The changeover unit (17) includes a clutch mechanism (51) comprised of an input member (38) and an output member (37, 21B) juxtaposed in an axial direction for movement in the axial direction and, also, rotatable relative to each other, a clutch groove (21Ba) provided in one of those members, and a clutch rolling element (54) provided in the other of those members and biased in a radial direction by the clutch groove (21Ba) so that it can be selectively engaged and disengaged.
