PROBLEM TO BE SOLVED: To provide a cooling duct, and the like, that can guide the cooling air suitably, even if the flow direction of cooling air flowing through the duct body, and the flow direction of cooling air flowing to the outside of the duct body are perpendicular ro each other.SOLUTION: A cooling duct includes a duct body 21 through which cooling air flows, an opening 23 formed in the duct body 21, on the upper side in the height direction perpendicular to the depth direction that becomes the flow direction of cooling air, and a perforated plate 22 provided in the opening 23, and guiding the cooling air flowing through the duct body 21 from the inside to the outside of the duct body 21, so that the cooling air is directed from the depth direction toward the height direction. |
