摘要： A shift-by-wire control system includes a parking lock device that brings an output shaft of an automatic transmission device to a lock state when a range switching unit switches to the P-range. The parking lock device brings the output shaft to a lock-release state when the range switching unit switches to another shift range. An electric motor actuates the range switching unit and the parking lock device in accordance with an instruction of an operator. A manual device transmits manual operation force of the operator to the parking lock device when the electric motor stops. The manual device includes a one-way transmission unit permitting transmission of the manual operation force in a direction toward the lock state, and prohibiting transmission of the manual operation force in a direction toward the lock-release state.

摘要： A radial inner portion of a rotor core, where a rotor core and a rotor shaft are connected, has an electromagnetically excessive capacity. A recess is provided at the radial inner portion of the rotor core. The recess is a cylindrical bore retracting in the axial direction from the front surface of the rotor core, facing to a reduction gear unit, toward the rear surface of the rotor core. A sun gear bearing, supporting a sun gear of the reduction gear unit, is disposed at least partly in the recess. Extending the sun gear bearing in the axial direction brings the effects of preventing inclination of the sun gear, improving transmission efficiency of the reduction gear unit, and producing a large output torque without increasing the overall size.

摘要： A rod-lock mechanism is provided in an automatic transmission for a vehicle. The rod-lock mechanism has an engaging pin which will be engaged with a rod when the rod is in its initial position, so as to hold the rod in its initial position. The rod-lock mechanism further has an electric actuator for driving the engaging pin when electric power is supplied, so that the engaging pin is brought out of engagement from the rod. A forced parking current supply unit controls electric power supply to the electric actuator. When the electric power is supplied to the electric actuator, the rod is moved in a direction of a parking position to bring a vehicle into a parking condition.

摘要： A plurality of concavities and convexities is provided on tips of all rotor teeth 24 of the SR motor 5. Depths of the concave portions α are deep on an edge side where a stator tooth 23 and rotor tooth 24 first approach and are shallow as a facing area between the stator tooth 23 and rotor tooth 24 increases. Therefore, magnetic resistance between the stator tooth 23 and rotor tooth 24 becomes high at an early stage of the stator tooth 23 and rotor tooth 24 facing each other and becomes low as the facing area between the stator tooth 23 and rotor tooth 24 increases. As a result, torque fluctuation can be suppressed at a time of a large current and a minimum generation torque can be increased at a time of a small current.
