Abstract
In a rotation input device, a planetary carrier, connected to an operation knob, rotatably supports a planetary gear which meshes with an outer teeth row provided for a sun gear, to which an output shaft is secured, and also meshes with an inner teeth row provided for an outer gear. A plunger provided for the sun gear is in elastic contact with a recess cam provided for the outer gear. A solenoid unit prevents rotation of the outer gear in accordance with an output of a magnetic sensor which faces a magnet provided for the output shaft.
