A sprinkler device has an inlet-driving assembly mounted in by a rotary seat, and an outlet valve whose one end is mounted through the rotary seat and in the inlet-driving assembly and the other end has multiple through holes. A spray nozzle assembly is mounted on the outlet valve and has multiple first and second spray holes communicating with the through holes of the outlet valve and the rotary seat, and has a block flange formed around a periphery thereof. A first and a second O-rings are sequentially mounted on the block flange. One end of the spray nozzle assembly is mounted through a cover mounted on the inlet driving assembly. Subjected to a same pressure from water filled in all parts of the sprinkler device, the first and second O-rings reduce friction between the block flange and the cover to enable a smooth rotation of the spray nozzle assembly.
