Abstract
A housing structure includes an exterior cover having an opening through which an interior of the exterior cover communicates with an exterior of the exterior cover, an interior cover disposed inside the exterior cover and facing the exterior cover with a clearance secured therebetween, an inward projection projecting from the exterior cover to the interior cover, and an outward projection projecting from the interior cover to the exterior cover. The inward projection and the outward projection define an airflow passage in the clearance between the exterior cover and the interior cover, and the airflow passage includes multiple bent portions. The outward projection is greater in width than the inward projection in an airflow direction toward the opening, and the airflow direction perpendicular to a direction in which the interior cover faces the exterior cover.
