PROBLEM TO BE SOLVED: To provide a water spray tube in which positioning of a water spray hole is simplified and clogging of the water spray hole is reduced, and to provide a joint for connecting the water spray tube.SOLUTION: A water spray tube 1 in which a water spray hole 3 is formed comprises a plane portion 2 in an outer surface of the tube, where the water spray hole 3 is formed. In addition, in this water spray tube 1, the inner surface of the tube at the site in which the water spray hole 3 is formed is in a projecting shape toward the inside, and an opening 3a of the inner surface side of the tube of the water spray hole 3 is formed in a projecting shape portion 5.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】 散水孔の位置決めを容易にすると共に、散水孔の詰まりが軽減された散水管及びその散水管を繋ぐための継手を提供する。【解決手段】 散水孔3が形成された散水管1は、管外面に平面部分2を有し、平面部分2に散水孔3が形成されている。加えて、この散水管1では、散水孔3が形成された位置の管内面は内側に向かって突出形状であり、散水孔3の管内面側の開口3aが突出形状部分5に形成されている。【選択図】 図2
