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 actuator includes a motor, a controller, a housing, and a terminal. The controller controls the motor. The housing holds a stator of the motor and the controller. The terminal electrically connects a coil of the stator to the controller. The terminal includes a fused portion electrically connected to the coil. The fused portion is compressed in a direction in parallel with an axial direction of the motor.

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: 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.
