<P>PROBLEM TO BE SOLVED: To provide a spout device capable of reducing the abrasion of a nozzle or stabilizing the rotation of the nozzle. <P>SOLUTION: The spout device is provided with: a flow-in chamber 12 into which cleaning water flows in; a guide member 10 having an opening part 14 making the inside of the flow-in chamber communicate with the outside; and a cylindrical body 40 provided inside the flow-in chamber to project the tip of a diameter reducing part to the outside of the guide member from the opening part and capable of allowing the cleaning water to flow out from the tip of a diameter reducing part. The cylindrical body has a spout hole 52 inclined to the center axis of the cylindrical body in an asymmetric relation in the tip of the diameter reducing part and communicating with the diameter reducing part. The cylindrical body swingingly revolves around the center axis of the flow-in chamber while being inclined to the center axis of the flow-in chamber in a state of being in contact with the guide wall 22, a ceiling wall and an opening wall and rotates around the center axis of the cylindrical body itself and the contact state of the cylindrical body with the ceiling wall when the cylindrical body swingingly revolves and or rotates is a nearly linear state or a nearly curved state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
