Patent ID: 8444065

Claim:
A water discharge device which is configured to discharge water in a wide region while changing a water discharge direction, comprising: a guide member including therein a formed inflow chamber into which the water flows and an opening which connects the inside of the inflow chamber to the outside of the inflow chamber; a tubular body including a small diameter portion having a smaller diameter than the opening and a large diameter portion having a larger diameter than the opening, the small diameter portion having a tip thereof projected to the outside of the guide member through the opening, at least the large diameter portion being disposed in the inflow chamber, the tubular body being configured to allow the water which has flowed into the inflow chamber to flow out of the tip of the small diameter portion; and a water sprinkling member connected to the tip of the small diameter portion so that the water sprinkling member is positioned outside the guide member, provided with a plurality of water discharge ports and including therein a formed water storage chamber connected to the plurality of water discharge ports, respectively, wherein the tubular body is configured to swing and revolve around the central axis of the inflow chamber while tilting from the central axis of the inflow chamber in a state where at least a part of the small diameter portion comes in contact with the opening by the water which has flowed into the inflow chamber, and is configured to rotate around the central axis of the tubular body itself, and the center of gravity of a rotor constituted of the tubular body and the water sprinkling member is positioned near the opening which is located near the center of swing at which the central axis of the tubular body tilted by the swinging revolution and the central axis of the inflow chamber intersect in a state where any water is not supplied to the water storage chamber of the water sprinkling member, whereas the center of gravity of the rotor is moved to a water sprinkling member side in a state where the water is supplied to the water storage chamber of the water sprinkling member.
