Document Type and Number:
WIPO Patent Application WO/2019/231249
Kind Code:
A1
Abstract:
The present invention relates to a shift-by-wire (SBW) device and, more specifically, to an actuator and reduction gear structure of a shift-by-wire device. A shift-by-wire device according to the present invention comprises: a housing; a motor which generates torque by means of an applied current; a hollow rotor shaft; a reduction gear which receives the transmission of the torque of the motor, converts same and transmits same to an output; an output shaft which passes through inside the rotor shaft, has an encoder magnet provided on one end thereof, has the other end directly connected to a manual shaft, and transmits the torque increased by means of the reduction gear to a detent plate; and a controller disposed inside the housing and for detecting the position of the output from the encoder magnet.
