Abstract
According to a case construction of the satellite-broadcast receiving converter of the present invention, air from the outside can enter and exit from a housing through a filter by way of a hole. Accordingly, a case and a sealing member can be prevented from being destroyed because of the expansion and contraction of air in the housing and, at the same time, water such as rain entering a cavity through the hole can be prevented from entering the housing deeper by the filter.
