• a rotary unit comprising a knob operation part exposed to the outside of the cover part, and a sensing part inserted in the knob operation part so as to be rotated by the knob operation part and to sense the rotation of the knob operation part;
• a control unit comprising a parking button for shifting a transmission to a parking range, a display part for displaying a working range of the transmission, and a sensor for sensing the rotation of the rotary unit;
• and
• a body part comprising a locking part coupled to or decoupled from the sensing part to restrict the rotation of the rotary unit, a cam in which one side of the sensing part is inserted to allow returning to an original position when the knob operation part is rotated, and a body receiving the locking part and the cam, wherein:
• the sensing part comprises a shaft, one end of the shaft being inserted in the knob operation part, the shaft having a through-hole formed to intersect with a longitudinal direction of the shaft in the vicinity of the other end thereof, and a moving block formed between both ends of the shaft;
• and
• the control unit comprises a substrate arranged between the knob operation part and the sensing part, and the parking button, the display part, and the sensor are electrically connected to the substrate.
