摘要： An actuator includes a manually operable portion that is operable to transmit rotation to an output shaft. The manually operable portion is provided such that the manually operable portion extends through a housing while at least a portion of the manually operable portion is exposed to an outside of the housing. In this way, even in a case where the actuator becomes inoperable, it is possible to change a shift range by rotating the output shaft through operation of the manually operable portion. It is only required to have a connection hole, which is conventionally provided at an outer wall of a transmission case, as a hole, which connects this rotary actuator to a shift range change mechanism. Therefore, it is sufficient to perform only a relatively small improvement, such as providing screw holes for fixing the actuator in a preexisting transmission.

摘要： A rotary actuator includes a motor, an output shaft, and a speed reducer. The motor includes a motor shaft rotating about an axial direction. The output shaft is disposed in parallel with the motor shaft. The speed reducer reduces a rotational speed of the motor and transmits rotation of the motor at a reduced rotational speed to the output shaft. The speed reducer includes a parallel-shaft type reducer that has a drive gear on the motor shaft and a driven gear on the output shaft. One side and the other side in the axial direction are defined as a first side and a second side, respectively. The motor is located on the first side of the speed reducer in the axial direction. The driven gear includes a teeth portion having a gear end surface on the first side of the teeth portion. The motor includes a stator having a stator end surface on the second side of the stator. The gear end surface is located on the first side of the stator end surface in the axial direction.

摘要： A rotary actuator is used in a shift-by-wire system for a vehicle. The actuator includes a motor, a controller, a housing, and a bus bar. The controller controls the motor. The housing holds a stator of the motor and the controller. The bus bar includes a terminal and a holder. The terminal electrically connects a coil of the stator to a control board of the controller. The holder is molded with a part of the terminal. The terminal includes a board-side arm that extends from the holder and a connecting pin that protrudes from the board-side arm toward the control board and that is connected to the control board. The board-side arm includes a stress releasing member that extends along an imaginary plane in parallel with the control board. The stress releasing member includes at least one curved portion at which the stress releasing member is curved or bent.

摘要： A rotary actuator is used in a shift-by-wire system for a vehicle. The rotary actuator includes a motor, a controller, a housing, and a biasing member. The controller controls the motor. The housing supports a rotor assembly of the motor and holds the controller. The biasing member biases the rotor assembly in an axial direction to eliminate a thrust movement gap between the rotor assembly and the housing.

摘要： A rotary actuator used in a shift-by-wire system of a vehicle includes: a motor; an output shaft arranged parallel to a rotation shaft of the motor; and a deceleration mechanism that decelerates rotation of the motor and transmits it to the output shaft. The deceleration mechanism includes a drive gear provided over a rotation axis of the rotation shaft and a driven gear provided over a rotation axis of the output shaft to mesh with the drive gear. The driven gear is a separate member from the output shaft and is loosely fitted to the output shaft.

摘要： An output portion is formed integrally with an output gear made of a magnetic material and is rotated integrally with the output gear. A yoke is placed at the output gear and includes first and second yokes. An arcuate gap, which extends along an arc that is centered at a rotational center of the output gear, is formed between the first yoke and the second yoke. A magnet is installed between one end of the first yoke and one end of the second yoke. Another magnet is installed between another end of the first yoke and another end of the second yoke. A Hall IC is placed in the arcuate gap and is movable relative to the yoke. Primary holes are formed between the rotational center and the yoke such that the primary holes extend through the output gear in a plate thickness direction of the output gear.

摘要： A rotary actuator for a shift-by-wire system of a vehicle includes a motor with a motor shaft, an output shaft disposed in parallel with the motor shaft, a speed-reducing mechanism configured to reduce a rotational speed of the motor and transmit the rotation of the motor to the output shaft, and a case housing the motor and the speed-reducing mechanism. The speed-reducing mechanism includes a first speed-reducing portion including a ring gear and a sun gear, and a second speed reducing portion including a drive gear and a driven gear. The drive gear and the driven gear are coaxially disposed with the motor shaft and the output shaft, respectively, to serve as parallel shafts type gears. The drive gear is disposed between the motor and the first speed-reducing portion in an axial direction of the motor.
