摘要： A rotation transmitting apparatus according to the present invention includes a first sun gear, a second sun gear, first planetary gears and second planetary gears. A carrier for supporting the respective planetary gears is integrally provided with a rotor of a speed change motor for changing a speed of rotation to be transmitted, so that the number of mesh portions in the gears is reduced. Further, the rotor is formed of a cylindrical shape and an input shaft for rotating the first sun gear is inserted into the rotor, so that a limited space is effectively used.

摘要： A vehicle steering device has a steering inhibition portion that enables the steering device to be switched between a steering inhibition application mode and a steering inhibition release mode--regardless of whether or not the vehicle is being steered by a driver. This arrangement avoids the need to determine whether or not the vehicle is being steered before determining whether or not to inhibit steering.
