Abstract
A range switching device includes: a range switching portion having an output shaft rotatably supported inside a housing and switchable to ranges corresponding to output shaft turning positions; a motor attached with its motor shaft spaced apart from a shaft center of the output shaft; a reducer mechanism linked to the motor and the range switching portion; and a control board controlling rotation of the motor. The reducer mechanism has a planetary gear reducer mechanism formed of a sun gear, planetary gears, an internal gear, and a carrier supporting the planetary gears, and a spur gear reducer mechanism formed of a pinion and a main gear linked to the pinion. The control board is installed oppositely to the output shaft and the motor.
