PURPOSE: A swing nozzle device for fountain is provided to be vertically rotated to each other and make the nozzle stick to horizontally rotate back and forth, thereby enabling water spouts which is sprayed through each nozzle to direct more splendid fountain by drawing brilliant curve with horizontal and vertical direction. CONSTITUTION: A swing nozzle device for fountain includes a water pipe(10), a first and a second gear box(20,30), a nozzle unit(40). The water pipe supplies the water for the fountain. A first gear boa includes a motor(21), a box case(22), a cam plate(23), a first spur gear(27), a linear rail(26), and the load end bearing(24). The motor is included in one side of the box case which axis-fixed to a water pipe. Cam plate is connected to axis-fix on the driving axis of the motor inside the box case. A first spur gear is connected to be rotatable in a water pipe which passes through the box case. A rack gear(25) which horizontally move in constant length long the linear rail is gear-combined in one side of the first spur gear. It is connected by a load end bearing in the eccentric position of the cam plate and one end of the rack gear. A second gear box includes a bottom plate(31), a fixing bevel gear(33), a box case(32), a rotation bevel gear(34), a second and third spur gear(35, 36). The bottom plate is connected to be rotatable in a first spur gear on upper side of the first gear box. The fixing bevel gear is connected to outer circumference of water pipe passing through the center of the bottom plate. The rotation bevel gear is gear-combined which respectively axis-supported to be rotatable in box case which is settled in bottom plate on both side of the fixing bevel gear. Inside the box case, rotation power of the rotation bevel gear is transferred in opposite direction by a second and the third gear. The nozzle unit includes a branch(41), a rotating pipe(42), a nozzle pipe(43), a nozzle(44). The nozzle unit connects to the upper part of the water pipe included in a second gear box. The branch and the third spur gear are connected to the rotating pipe to be rotatable. Vertical is formed by constant height in outer circumference of the rotating pipe, the upper part of the vertical is horizontally formed in constant length which is to be symmetry to each other. In outer circumference of a horizontal part, a nozzle has a plurality of nozzle pipe in constant interval.
