Abstract: The present invention relates to an injector separating device using a vibrator and more specifically, to an injector separating device using a vibrator which enables periodic preventive maintenance for preventing an injector from being stuck by carbons leaked between an engine head wall and the injector caused by the pressing pressure leaked by a malfunction of a copper washer for sealing the engine head and the injector; automatically separates the injector, which is manually separated in the past, when the stuck injector has to be replaced by a loss of the function of the stuck injector by using the vibrator generating vibration in safe and easy ways; and safely separates the injector and coupling components of the injector without damage via a vibrator control function capable of controlling the intensity of the vibrator. The injector separating device using the vibrator according to the present invention includes a screw thread on the outer circumference of the upper part and separates the injector mounted on a cylinder head. The present invention includes a first injector separation head in which a first coupling hole including an inner screw thread having a predetermined length is penetrated and where first coupling hole is screw-joined to the screw thread of the injector; and a pneumatic vibrator which is composed of a piston rod which includes a first screw unit including a screw thread for being screw-joined to the first coupling hole on the lower part and which is fixed to the first injector separation head and a cylinder body where compressed air flows into the inside in order to apply vibration to the injector and which is linearly reciprocated along the piston rod.
