Disclosed is a disconnector-type clutch for a rear wheel-driving device in a 4-wheel driving electric vehicle, which can eliminate a loss in the driving force due to a slip of friction plates disposed in a multiple disc clutch by transmitting power to rear wheels using the disconnector-type clutch, instead of the multiple disc clutch in 4-wheel driving, and can prevent a loss in the energy by preventing a differential from unnecessarily rotating when rear wheels are drawn by a driving force of front wheels in 2-wheel driving in which a rear-wheel driving motor is not driven by installing the disconnector-type clutch at a rear end of the differential. The disconnector-type clutch includes an actuator motor generating rotation power, a worm gear connected to the actuator motor, a screw rotating in engagement with the worm gear, a first push case converting a rotary motion of the screw into a linear reciprocating motion, a second push case assembled with the first push case, a first spring installed between the first push case and the second push case, a second spring installed at an exterior side of the second push case to provide a restoration force, a shifting fork connected to the second push case and moving forward and backward, and a sleeve connected to the shifting fork and connecting or disconnecting the first rear-wheel driving shaft and the second rear-wheel driving shaft.
