Summary:PROBLEM TO BE SOLVED: To provide a blast pipe that, even when the volume of air taken in from an inlet is increased, can exhaust air to be exhausted from an outlet in a short direction of an opening shape of the outlet while unevenness in wind speed is reduced.SOLUTION: A blast pipe includes a passage part and a plurality of reduction parts. The passage part has an introduction passage part that has an inlet present at one end, and a first bent passage part that is bent in the middle of the introduction passage part and has a passage space formed in a rectangular cross-sectional shape. One of the reduction parts is provided as a first reduction part formed of a blocking part that is present along one direction of the cross-sectional shape in part of the passage space of the first bent passage part and blocks the flow of air, a lower opening that is formed in a long opening shape along the one direction of the cross-sectional shape and is present in contact with a bottom face to be a reference of the passage space of the first bent passage part, and an upper opening that is present along the one direction of the cross-sectional shape and present at a position above and separated from the lower opening.SELECTED DRAWING: Figure 4 【課題】入口から取り入れる空気の風量を増加させた場合でも、出口から排出させる空気を出口の開口形状の短手方向での風速のむらが抑制された状態で排出できる送風管等を提供する。【解決手段】送風管は、通路部と複数の抑制部とを備え、通路部は、入口が一端に存在する導入通路部と導入通路部の途中から曲げられて通路空間が長方形状の断面形状からなる第1曲げ通路部とを有し、抑制部の1つは、第1曲げ通路部の通路空間の一部に断面形状の一方向に沿って存在して空気の流れを遮断する遮断部と、前記断面形状の一方向に沿って長い開口形状からなるとともに第1曲げ通路部の通路空間の基準とする底面に接して存在する下開口部と、前記断面形状の一方向に沿って存在するとともに下開口部よりも上方の位置に離れて存在する上開口部とで構成される第1抑制部として設けられている。【選択図】図4
