A case structure of an in-wheel includes a case of the in-wheel motor, a ventilation hole that allows air to flow between an inner side and an outer side of the case, and a cover that covers the ventilation hole from the outer side of the case. The cover includes an air hole that is located below the opening portion of the ventilation hole and that opens to the outer side of the cover, and an air chamber that holds air above the air hole. The air chamber is divided into a first region located above the opening portion, and a second region located below the opening portion. The second region has a volume that holds air that suppresses a water level of water in the cover to be below the opening portion when water enters inside the cover from the air hole.
