Abstract: PURPOSE: A variable valve timing device is provided to reduce production costs, and to improve the efficiency of an engine because power transmission is unnecessary when vale timing is not needed to be controlled. CONSTITUTION: A variable valve timing device comprises a cam shaft holder(20), a cam sprocket, a rotary shaft(40), first and second driven bevel gears, a screw nut(50), and a gear control unit. The cam sprocket transfers torque to a cam shaft. The rotary shaft is formed in the cam shaft holder, and movable threads are formed. The first and second driven bevel gears are respectively formed in both ends of the rotary shaft. The screw nut moves in a longitudinal direction of the rotary shaft according to the rotation of the first or second driven bevel gear. The screw nut changes relative rotational angles of the cam shaft and cam sprocket. The gear control unit selectively rotates the fist or second driven bevel gear.
