To provide a smoke exhaust duct in which sticking of driving of a valve body, provided in the smoke exhaust duct, is restrained even if dew condensation water is produced in the smoke exhaust duct, or an extraneous material enters into the smoke exhaust duct, in a smoke exhaust duct interconnecting a smoke exhaust passage provided in a power storage device and an outdoor.SOLUTION: A smoke exhaust duct includes a lower case 30, an upper case 31, and a valve body 32, where the valve body 32 has a shank provided above, and interconnects an outdoor and a smoke exhaust, by rotating around the shank from a blockage position for blocking a ventilation passage. The lower case 30 has support parts 47, 48 for supporting the shank so that the valve body 32 is rotatable, and the support parts 47, 48 are formed to cover the shank from above. An upward recess is formed at a portion above the support parts 47, 48, in the internal surface of the upper case 31, and when viewing the recess and the support parts 47, 48, from above, at least a part of the support parts 47, 48 is located in the recess.SELECTED DRAWING: Figure 4
【課題】蓄電装置内に設けられた排煙通路と車室外とを連通する排煙ダクトにおいて、排煙ダクト内で結露水が生じたり、排煙ダクト内に異物が入り込んだとしても、排煙ダクト内に設けられた弁体の駆動が固着することが抑制された排煙ダクトを提供する。【解決手段】排煙ダクトは、ロアーケース30と、アッパーケース31と、弁体32とを含み、弁体32は、上部に設けられた軸部を有し、通気通路を遮断する遮断位置から軸部を中心として回転することで、車室外と排煙通路とを連通し、ロアーケース30は、弁体32が回転可能なように軸部を支持する支持部47,48を有し、支持部47,48は、軸部を上方から覆うように形成され、アッパーケース31の内表面のうち、支持部47,48の上方に位置する部分には、上方に向けて凹部が形成されており、凹部および支持部47,48を上方から視ると、支持部47,48の少なくとも一部は凹部内に位置する。【選択図】図4
