Abstract: A rotary actuator is used in a shift-by-wire system for a vehicle. A speed reducer includes a ring gear and a sun gear and reduces a rotational speed of the motor. An output shaft outputs rotation of the motor at a reduced rotational speed by the speed reducer. A regulating pin is disposed in a fixing member and allows the sun gear to revolve around a rotational axis of the motor and to rotate about an eccentric axis. The regulating pin is a separate member from the fixing member. The regulating pin has a strength equal to or greater than a maximum torque reaction force received from the sun gear. A first difference in hardness between an engaging portion and the sun gear is set to be less than a second difference in hardness between the fixing member and the sun gear.

Abstract: An output shaft includes a shaft hole with which a shaft is fittable, rotates by torque output from a motor, and outputs torque to the shaft. A magnet holder includes a holder hole with which the shaft is fittable and is rotatable together with the shaft. A magnet is disposed on the magnet holder. An angle sensor is capable of detecting magnetic flux from the magnet and outputs a signal corresponding to a rotation angle of the magnet holder. A play amount between the shaft and the shaft hole is set to a first predetermined value or larger. A play amount between the shaft and the holder hole is set to a second predetermined value or smaller.

Abstract: A rotary actuator is used in a shift-by-wire system for a vehicle. The actuator includes a motor, a controller, an upper case, a lower case, a case fastening member, and a board fixing member. The controller controls the motor. The upper case is made from resin and houses the controller. The lower case houses the motor together with the upper case. The case fastening member is made from metal and fastens the upper case and the lower case to each other. The board fixing member fixes a board of the controller to the case fastening member.

Abstract: A rotary actuator for use in a shift-by-wire system of a vehicle includes a motor, a controller for controlling the motor, and a case housing the motor and the controller. An upper case of the case includes a resin molded body, which integrally has a housing that houses the motor and a connector that is used for external connection, and a plurality of external connection terminals, which are embedded in the resin molded body and are capable of connecting the controller to an outside member. Each of the external connection terminals includes a base protruding into an installation space for a control board in a board extending direction, a bend bent from the base toward the control board, and a tip portion extending from the bend to the control board.

Abstract: 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.

Abstract: 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.

Abstract: A rotary actuator includes a rotation shaft rotatably driven by a motor, an internal gear provided on an outer side of the rotation shaft in a radial direction of the rotation shaft, a rotation output section provided between the rotation shaft and the internal gear in the radial direction to reduce a rotation speed outputted from the rotation shaft and to output a power in conjunction with the internal gear, a cylindrical housing portion fixed to the internal gear, and an attachment member integrated with an outer wall of the housing portion. The internal gear has a protrusion protruding from an outer wall of the internal gear, and the housing portion has a recess into which the protrusion is inserted. The attachment member has an attachment hole that is different from the recess in position in a circumferential direction of the housing portion.
